Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567612, here are decompositions:

53 + 31567559 = 31567612
59 + 31567553 = 31567612
101 + 31567511 = 31567612
521 + 31567091 = 31567612
563 + 31567049 = 31567612
569 + 31567043 = 31567612
701 + 31566911 = 31567612
773 + 31566839 = 31567612

Showing the first eight; more decompositions exist.
