S287 fully tested n=80-85k
PFGW version 3.7.7

Prime found for 1k:
1292*287^81511+1

95 k's remain.
Testing continues to n=100k

For 75k<n<100k using P1e6 weight I calculated:
k=1292 had 8.24% chance of prime, so I found 78th hardest k remaining

Default Reserving 41*264^n+1

Hi

I'd like to test this candidate.
I'll start with a small range (200k-210k) to get a feeling for this but I think I'll continue up to highe values.

S287 fully tested n=85-90.3k
PFGW version 3.7.7

Prime found for 4k's:
4474*287^86350+1
3754*287^86670+1
5266*287^89464+1
2096*287^90201+1

91 k's remain.
Testing continues to n=100k

For 75k<n<100k using P1e6 weight I calculated:

k=3754 had 6.74% chance of prime, so I found 56th hardest k remaining (of 95)
k=5266 had 5.52% chance of prime, so I found 39th hardest k remaining (of 95)
k=2096 had 10.33% chance of prime, so I found 91st hardest k remaining (of 95)
