Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613090, here are decompositions:

37 + 31613053 = 31613090
109 + 31612981 = 31613090
139 + 31612951 = 31613090
151 + 31612939 = 31613090
199 + 31612891 = 31613090
331 + 31612759 = 31613090
337 + 31612753 = 31613090
463 + 31612627 = 31613090

Showing the first eight; more decompositions exist.
