Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525146, here are decompositions:

19 + 31525127 = 31525146
43 + 31525103 = 31525146
109 + 31525037 = 31525146
139 + 31525007 = 31525146
157 + 31524989 = 31525146
179 + 31524967 = 31525146
283 + 31524863 = 31525146
307 + 31524839 = 31525146

Showing the first eight; more decompositions exist.
