Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511796, here are decompositions:

23 + 31511773 = 31511796
53 + 31511743 = 31511796
67 + 31511729 = 31511796
83 + 31511713 = 31511796
227 + 31511569 = 31511796
257 + 31511539 = 31511796
263 + 31511533 = 31511796
269 + 31511527 = 31511796

Showing the first eight; more decompositions exist.
