Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525234, here are decompositions:

5 + 31525229 = 31525234
23 + 31525211 = 31525234
71 + 31525163 = 31525234
107 + 31525127 = 31525234
113 + 31525121 = 31525234
131 + 31525103 = 31525234
197 + 31525037 = 31525234
227 + 31525007 = 31525234

Showing the first eight; more decompositions exist.
