Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525204, here are decompositions:

3 + 31525201 = 31525204
41 + 31525163 = 31525204
83 + 31525121 = 31525204
101 + 31525103 = 31525204
167 + 31525037 = 31525204
173 + 31525031 = 31525204
197 + 31525007 = 31525204
311 + 31524893 = 31525204

Showing the first eight; more decompositions exist.
