Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525366, here are decompositions:

23 + 31525343 = 31525366
83 + 31525283 = 31525366
137 + 31525229 = 31525366
239 + 31525127 = 31525366
263 + 31525103 = 31525366
359 + 31525007 = 31525366
503 + 31524863 = 31525366
557 + 31524809 = 31525366

Showing the first eight; more decompositions exist.
