69660 is the least number N such that N is 215 mod 323, N is 0 mod 215 and N is 6 mod 13...
then you have other values using Chinese remainder theorem

I agree that 69660 == chinese([Mod(215,323), Mod(0,215), Mod(6,13)]), and I'm prepared to assume that Pg(69660) is prime. But why should that make us think that
((2^18752301)*10^564501+2^18752291)
is likely to be prime?
