Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525212, here are decompositions:

11 + 31525201 = 31525212
29 + 31525183 = 31525212
109 + 31525103 = 31525212
181 + 31525031 = 31525212
223 + 31524989 = 31525212
349 + 31524863 = 31525212
373 + 31524839 = 31525212
419 + 31524793 = 31525212

Showing the first eight; more decompositions exist.
