Hi David,
I avoided exceeding 'flintmax', minimized multiplication, division and conditional statements. For small n's, like in test 7, | only used a simple sieving algorithm. I also checked my solution with Elixir, and Java and I still get the same result for test 7.
I initially did a sieving algorithm, but it was not efficient enough for large n. I did not consider splitting with two different algorithms.
