Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525038, here are decompositions:

7 + 31525031 = 31525038
11 + 31525027 = 31525038
31 + 31525007 = 31525038
47 + 31524991 = 31525038
71 + 31524967 = 31525038
101 + 31524937 = 31525038
199 + 31524839 = 31525038
229 + 31524809 = 31525038

Showing the first eight; more decompositions exist.
