Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525090, here are decompositions:

53 + 31525037 = 31525090
59 + 31525031 = 31525090
83 + 31525007 = 31525090
101 + 31524989 = 31525090
197 + 31524893 = 31525090
227 + 31524863 = 31525090
251 + 31524839 = 31525090
281 + 31524809 = 31525090

Showing the first eight; more decompositions exist.
