OK I'll start testing within a couple of days for n=300k-500k. Thanks.

k=32767:

This one is currently reserved by Diep for n=5M-30M. Since it is so low weight I thought it would be interesting to see if there were any more primes up to n=1M.

Double-check complete to n=50K. 4 previously found primes confirmed. No problems found.

First-time check complete for n=50K-1M. No primes found.

This is a very low-weight k! :-)

Results attached.
