Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536566, here are decompositions:

37 + 31536529 = 31536566
67 + 31536499 = 31536566
163 + 31536403 = 31536566
379 + 31536187 = 31536566
547 + 31536019 = 31536566
619 + 31535947 = 31536566
739 + 31535827 = 31536566
757 + 31535809 = 31536566

Showing the first eight; more decompositions exist.
