Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525012, here are decompositions:

5 + 31525007 = 31525012
23 + 31524989 = 31525012
149 + 31524863 = 31525012
173 + 31524839 = 31525012
443 + 31524569 = 31525012
479 + 31524533 = 31525012
503 + 31524509 = 31525012
593 + 31524419 = 31525012

Showing the first eight; more decompositions exist.
