Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613258, here are decompositions:

31 + 31613227 = 31613258
67 + 31613191 = 31613258
139 + 31613119 = 31613258
151 + 31613107 = 31613258
277 + 31612981 = 31613258
307 + 31612951 = 31613258
367 + 31612891 = 31613258
499 + 31612759 = 31613258

Showing the first eight; more decompositions exist.
