Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525036, here are decompositions:

5 + 31525031 = 31525036
29 + 31525007 = 31525036
47 + 31524989 = 31525036
173 + 31524863 = 31525036
197 + 31524839 = 31525036
227 + 31524809 = 31525036
239 + 31524797 = 31525036
269 + 31524767 = 31525036

Showing the first eight; more decompositions exist.
