Lars and other interested folk:

I have been away for a few days, and the following are all first primes - sorry for the one over 150000, I shall stop testing these.

150506*5^22667+1
33860*5^23213+1
6772*5^23214+1
104624*5^23443+1
137714*5^23863+1
96806*5^24813+1
106418*5^25077+1
59302*5^25228+1

All remaining candidates are tested to n=25228. After these and Lars's discovery there are 195 remaining candidates.

I will take on the first 12 of the remainder and check to n=200000, namely

2822
3706
4276
4738
5048
5114
5504
6082
6436
7528
8644
9248
