Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525164, here are decompositions:

37 + 31525127 = 31525164
43 + 31525121 = 31525164
61 + 31525103 = 31525164
127 + 31525037 = 31525164
137 + 31525027 = 31525164
157 + 31525007 = 31525164
173 + 31524991 = 31525164
197 + 31524967 = 31525164

Showing the first eight; more decompositions exist.
