Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525270, here are decompositions:

3 + 31525267 = 31525270
41 + 31525229 = 31525270
59 + 31525211 = 31525270
107 + 31525163 = 31525270
149 + 31525121 = 31525270
167 + 31525103 = 31525270
233 + 31525037 = 31525270
239 + 31525031 = 31525270

Showing the first eight; more decompositions exist.
