Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519996, here are decompositions:

59 + 31519937 = 31519996
107 + 31519889 = 31519996
173 + 31519823 = 31519996
227 + 31519769 = 31519996
293 + 31519703 = 31519996
317 + 31519679 = 31519996
509 + 31519487 = 31519996
569 + 31519427 = 31519996

Showing the first eight; more decompositions exist.
