295K digits, PrimeGrid's Proth Primes are rapidly approaching 300K digits
(after having been below 200K for quite some time, as we finished
through n=666666).

This is my 52nd top5000 prime, of which 46 are still on the
list; puts me at 18th on the top20 list by number of primes.
(Sorry: primegrid primes count?)
