Thanks for the update, Mark. Will update MathWorld.

Cool. Thanks again for continuing the search and providing an update on your progress!

Completed to 450,000. No new primes, but continuing.

I will stop at 465,000 as the tests are taking about 3 hours each. More sieving is needed before I could continue.

Thanks again. Small clarification: does that mean you have *already* reached 465,000 and have now stopped, or that you expect to do so soon? (Basically, should I update MathWorld yet.)

I completed to 465,000, but I decided to continue to 500,000 just because I like round numbers like that. I will eventually post the remaining numbers to be tested and the sieving code. I'm getting a new iMac soon, so I think that the sieving code could easily be ported to a GPU which should make it noticeably faster.
