Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525048, here are decompositions:

11 + 31525037 = 31525048
17 + 31525031 = 31525048
41 + 31525007 = 31525048
59 + 31524989 = 31525048
239 + 31524809 = 31525048
251 + 31524797 = 31525048
257 + 31524791 = 31525048
281 + 31524767 = 31525048

Showing the first eight; more decompositions exist.
