pg(215) and pg(541456) are probable primes

215 and 541456 are 215 mod 307

with pfgw I tried if are probable primes:

pg(215+1763*307*2), pg(215+1763*307*3)...

upto pg(215+1763*307*18) the numbers have all very small factors...so they are not probable prime...

whereas pg(215+1763*307*19) has no small factor and I am running a prp test on it
