Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613124, here are decompositions:

5 + 31613119 = 31613124
7 + 31613117 = 31613124
17 + 31613107 = 31613124
71 + 31613053 = 31613124
97 + 31613027 = 31613124
163 + 31612961 = 31613124
173 + 31612951 = 31613124
211 + 31612913 = 31613124

Showing the first eight; more decompositions exist.
