Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525110, here are decompositions:

7 + 31525103 = 31525110
73 + 31525037 = 31525110
79 + 31525031 = 31525110
83 + 31525027 = 31525110
103 + 31525007 = 31525110
173 + 31524937 = 31525110
271 + 31524839 = 31525110
313 + 31524797 = 31525110

Showing the first eight; more decompositions exist.
