If you found it using Prime95, mprime, mlucas, gpuOwl, or any other software that we talk about in the forum you can tell us more so it can be verified.

Is your number in the form 2p-1 where the p is an already known prime (which is a requirement for a Mersenne Prime)?

Is it some other special form? If so which form? And how big is the input number (like the p above)?

What software did you use to check it? How long did it take to check and on what kind of computer?

Because before you can claim a prize, the number has to be verified by a different user, using a different type of computer and different type of software. We have folks here that can help figure a path forward.

156635789 you can look with the program you want?

What program did you use? With out telling that to us it is hard for us to take you seriously.

For the sake of things we will assume that you tested 2156635789-1
How did you choose that number? It does not show that it was assigned via PrimeNet.
It did not have the normal level of TF and P-1 work done on it first (to try to find potential factors).

If you used any of the programs that I mentioned above and it said that it is prime, submit the results file to PrimeNet via the Manual Results form: https://www.mersenne.org/manual_result/
And then find the last save file and email it to George:

If you don't know where the results file is, that may be an issue. Because that is part of where your proof that you ran the exponent to completion. Also the last save file helps to verify it too. Did you run an L-L test or a PRP?

156635789 shows no PRP test result or assignment, no LL test result or assignment, no normally preceding P-1 factoring result or assignment, and inadequate TF to date.

So, it seems to me highly unlikely, and I tentatively classify it for now as a dubious claim.
No TF, P-1, LL or PRP manual assignment can be obtained for it, because there is a current TF assignment active for user Runtime Error.
https://www.mersenne.org/assignments...p_hi=156635790

For anyone finding a new Mersenne prime, or having a software malfunction that gave the appearance of such, there's advice in https://www.mersenneforum.org/showpo...5&postcount=14 how to proceed

Hint, get private confirmation by others, and cooperate quietly with the process for that and official GIMPS press release Before the GIMPS press release is issued by George Woltman, make no specific other public announcement, not even here.

Posting an unconfirmed claim instead of going through the proper channels is considered bad form, and may get the poster viewed as a crank. It may also affect award of a prize claim. "Non-compliance may result in award disqualification."

I view https://www.mersenne.ca/exponent/156635789 as recommending TF to 78 bits, P-1 to B1=1540000,B2=43120000 before any PRP It's a bit large for reliable LL which has weaker error checking.
I'd be happy to throw some cycles at proving or disproving the current claim. Perhaps others would too. Coordination is preferred.
I've taken the liberty of queuing up its P-1 factoring to the bounds above.

That's ok, you can publish it here.

This will be a valuable learning exercise. Let's review the formula that gave you a patently wrong result (see above*).

*just in case you don't know what that message means: Recall that a prime has no factors except 1 and itself. but this one has a factor which is not 1 or itself. What conclusions do you draw from this?

Well done. This might be a a new speed record for empirically dispatching a dubious claim.

Please document how you found the factor.
