I note R916 fell pretty quickly, and with a double hit.
IIRC, it sieves to 1e6, but also eliminates numbers with algebraic factorizations. The difficulty is a rough guess to the number of tests needed at 1e12. The reason it sieves to 1e6 is because many of the k are larger than 1e5. It isn't perfect, but hopefully more accurate.
