Sure will, that ain't the only (potential) 10M digit prime. It'd also be nice if the second highest prime weren't a Mersenne for a change.

Returning 275 - 280 T, 9 factors found. Taking 290 - 295 T.

Taking 295 - 300 T for another chunk that will be done tomorrow.

Returning 280 - 285 T, 9 factors found.

If anyone is interested, this means the sieve has progressed past 2^48.

Returning 290 - 295 T and 295 - 300 T, 12 and 7 factors found.

Taking 310 - 315 T and 315 - 320 T.

I've also updated the attached sieve file in the first post. All factors to 305 T have been removed from it, and also the algebraic factors now (of which there were 411). There are 14,169 candidates remaining in the sieve.

Returning 330 - 335 T and 335 - 340 T, 6 and 4 factors found.

Taking 340 - 345 T and 345 - 350 T.

Since there seems to be a lack of interest in this, I think once I get to 350 T I'm going to suspend it. Obviously I'll keep all the factors found and the latest sieve file safe. Perhaps when LLR tests of 10m digit numbers run in hours instead of days there will be more interest.
