Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597528, here are decompositions:

191 + 31597337 = 31597528
401 + 31597127 = 31597528
647 + 31596881 = 31597528
821 + 31596707 = 31597528
857 + 31596671 = 31597528
1031 + 31596497 = 31597528
1091 + 31596437 = 31597528
1109 + 31596419 = 31597528

Showing the first eight; more decompositions exist.
