Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613892, here are decompositions:

31 + 31613861 = 31613892
53 + 31613839 = 31613892
59 + 31613833 = 31613892
73 + 31613819 = 31613892
109 + 31613783 = 31613892
173 + 31613719 = 31613892
223 + 31613669 = 31613892
263 + 31613629 = 31613892

Showing the first eight; more decompositions exist.
