Congrats on a nice prime! It's the best to counter false primes with real ones! As for the composite by Thomas, let's hope it was a typo.

I'm using it for about 3 years now for finding quite a lot of "true" primes... Seems, that this problem isn't restricted to grobie's machine. And it doesn't seem to be SSE2 related, since on the Athlon LLR uses the nonSSE2 code. Last fiddled with by Thomas11 on 20060303 at 10:16

Another pair of primes:
155*2^3103121 (93416 digits) 155*2^3106221 (93509 digits) I verified them on a second machine, let's see Chris Caldwell's final check...

They were just confirmed to be primes.
A nice pair of neigbours, congrats!

Nice primes Thomas! k=155 is so prolific but not so high weight, for example less then k=23 which has just a few primes.
