Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567516, here are decompositions:

3 + 31567513 = 31567516
5 + 31567511 = 31567516
89 + 31567427 = 31567516
359 + 31567157 = 31567516
467 + 31567049 = 31567516
653 + 31566863 = 31567516
677 + 31566839 = 31567516
719 + 31566797 = 31567516

Showing the first eight; more decompositions exist.
