Wonderful work, by all concerned.

PrimeMogul is cautious and runs an old OpenPFGW

as a validator. He has marked the -tp proof of

http://primes.utm.edu/primes/page.php?id=95248

as "external", i.e. tedious to do at home.

But I expect that Chris's run will eventually

"internalize" the proof, after a week, or so,

rather than a PrimeGrid day.
