Sierp base 2 even k's 88996, 90646, and 101746 are at n=250K; nothing to report; continuing to n=1M.

I've also doublechecked all 78557<k<271129 to n=250K. No problems found. I may or may not continue this doublecheck to n=500K.

Sierp base 2 even k's 88996, 90646, and 101746 are at n=400K; nothing to report; continuing to n=1M.

I also decided to continue doublechecking all 78557<k<271129 to n=500K and am doing that in conjunction with the above 3 k's. No problems have been found to n=400K. For n>500K, I will continue with only the 3 even k's.

88996*2^408600+1 is prime

This finally eliminates one of the Sierp base 2 even k's. 2 still remain.

Sierp base 2 even k's 90646 and 101746 are at n=500K; 1 prime found for k=88996 arleady reported; continuing to n=1M.

I have now completed the doublecheck on the entire 2nd conjecture to n=500K. No problems were found. 33 k's are remaining. No more doublechecking will be done. Things should move quickly now. :-)

Sierp base 2 even k's are at n=600K; nothing to report; continuing.

Sierp base 2 even k's are at n=700K; nothing to report; continuing.

Sierp base 2 even k's are at n=800K; nothing to report; continuing.

Sierp base 2 even k's are at n=900K; nothing to report; continuing to n=1M. ETA is < 2 weeks.

At n=1M, I'd like to make a team drive out of these and the 2 Riesel base 2 even k's for n=1M-2.5M. The Riesel k's were sieved to what the optimum depth was long ago but much efficiency will be gained by sieving all 4 k's together after catching up the Sierp k's.

Releasing 2 even-k values (k=351134 and 478214) at n=1.04M.
Sieve file with ~18000 pairs up to n=2.5M (p=5T) available.

Reserving Riesel even-k k=351134 & 478214 and Sierp even-k 90646 & 101746 for n=1M-2.5M for team drive #6.

Sierp base 2 even k's 90646 & 101746 are complete to n=1M; nothing to report; released to the future team drive mentioned in the last post.
