Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477324, here are decompositions:

3 + 31477321 = 31477324
23 + 31477301 = 31477324
257 + 31477067 = 31477324
443 + 31476881 = 31477324
503 + 31476821 = 31477324
701 + 31476623 = 31477324
773 + 31476551 = 31477324
863 + 31476461 = 31477324

Showing the first eight; more decompositions exist.
