Good point, I thought I did but I can no longer find the sieve file to verify so I'll do it again.

Base 158 from 30 - 40k finished.

Found (158^33873-1)^2-2 is prime (148,951 digits)

I'll continue on base 158 from 40-50k

To close the loop here, I finished searching base 156 from 10 - 20k and no primes were found.

Finished searching base 158 from 40-50k but found no primes.

I'll release the reservation on 158 here thanks.
