Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525126, here are decompositions:

5 + 31525121 = 31525126
23 + 31525103 = 31525126
89 + 31525037 = 31525126
137 + 31524989 = 31525126
233 + 31524893 = 31525126
263 + 31524863 = 31525126
317 + 31524809 = 31525126
359 + 31524767 = 31525126

Showing the first eight; more decompositions exist.
