Only one more to go for RPS to have reached 500 primes! :banana::banana::banana:

201 799611 is prime.
Sadly, this was the 498th prime, earlier Wednesday.
201 had been reported complete to 840k- I failed to check the primes file after noting the search file complete to 800k and starting a new search range.
