Trial division to 10^12

Primality testing (223^32768+1)/2/65537 [N-1/N+1, Brillhart-Lehmer-Selfridge]
Running N-1 test using base 3
Running N+1 test using discriminant 7, base 1+sqrt(7)
Calling N-1 BLS with factored part 0.01% and helper 0.01% (0.05% proof)
(223^32768+1)/2/65537 is Fermat and Lucas PRP! (530.7552s+0.0025s)
