Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596724, here are decompositions:

11 + 31596713 = 31596724
17 + 31596707 = 31596724
53 + 31596671 = 31596724
113 + 31596611 = 31596724
227 + 31596497 = 31596724
251 + 31596473 = 31596724
311 + 31596413 = 31596724
431 + 31596293 = 31596724

Showing the first eight; more decompositions exist.
