Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613202, here are decompositions:

11 + 31613191 = 31613202
31 + 31613171 = 31613202
59 + 31613143 = 31613202
83 + 31613119 = 31613202
149 + 31613053 = 31613202
211 + 31612991 = 31613202
233 + 31612969 = 31613202
241 + 31612961 = 31613202

Showing the first eight; more decompositions exist.
