And one more for PCZ:

45652*5^229218+1 is prime.

Congratulation.

We appear to be doing rather well as a team - I had not realised we had so many top 5000 !!!

Congrats!

The primes seem to come fewer and further between, but size matters in this case :)

This is fairly heavy k and removes almost 1% of the remaining composites from the dat file. The funny thing is that this was found on the same PC that found my previous prime. The other PCs are still chugging away without finding any primes.

Well, just remember everyone get's lucky sometimes. And now hope that includes every computer
