Thanks - maybe this is the biggest prime for NPLB so far ? Thank you for reminding me to report it. The chances for me to remember it by my self was less than 1/(333*2^2785626-1).

I have updated the instructions for reporting top-5000 primes in the first post of this thread. It had become outdated after the top-5000 site was updated.

If you are new to reporting top-5000 primes please let me know if you find any problems in the instructions.

That was lucky!
In a couple days it wouldn't have fit. Now it will stay there forever

Actually not so lucky. More skill. :-)

Over the last few months I have periodically been putting my machines on either port 2000 or port 9000 to keep them barely into the top-5000 range. It looks like I need to do that again for port 2000. I'll probably move some machines over next week.

I'd welcome a big hitter or two on either port for awhile.
