Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613232, here are decompositions:

5 + 31613227 = 31613232
41 + 31613191 = 31613232
61 + 31613171 = 31613232
89 + 31613143 = 31613232
113 + 31613119 = 31613232
179 + 31613053 = 31613232
241 + 31612991 = 31613232
251 + 31612981 = 31613232

Showing the first eight; more decompositions exist.
