Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525134, here are decompositions:

7 + 31525127 = 31525134
13 + 31525121 = 31525134
31 + 31525103 = 31525134
97 + 31525037 = 31525134
103 + 31525031 = 31525134
107 + 31525027 = 31525134
127 + 31525007 = 31525134
167 + 31524967 = 31525134

Showing the first eight; more decompositions exist.
