Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613268, here are decompositions:

19 + 31613249 = 31613268
41 + 31613227 = 31613268
97 + 31613171 = 31613268
131 + 31613137 = 31613268
149 + 31613119 = 31613268
151 + 31613117 = 31613268
241 + 31613027 = 31613268
277 + 31612991 = 31613268

Showing the first eight; more decompositions exist.
