Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510732, here are decompositions:

41 + 31510691 = 31510732
53 + 31510679 = 31510732
101 + 31510631 = 31510732
179 + 31510553 = 31510732
191 + 31510541 = 31510732
509 + 31510223 = 31510732
563 + 31510169 = 31510732
593 + 31510139 = 31510732

Showing the first eight; more decompositions exist.
