Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525216, here are decompositions:

3 + 31525213 = 31525216
5 + 31525211 = 31525216
53 + 31525163 = 31525216
89 + 31525127 = 31525216
113 + 31525103 = 31525216
179 + 31525037 = 31525216
227 + 31524989 = 31525216
353 + 31524863 = 31525216

Showing the first eight; more decompositions exist.
