Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525116, here are decompositions:

13 + 31525103 = 31525116
79 + 31525037 = 31525116
89 + 31525027 = 31525116
109 + 31525007 = 31525116
127 + 31524989 = 31525116
149 + 31524967 = 31525116
179 + 31524937 = 31525116
223 + 31524893 = 31525116

Showing the first eight; more decompositions exist.
