Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576756, here are decompositions:

5 + 31576751 = 31576756
17 + 31576739 = 31576756
47 + 31576709 = 31576756
53 + 31576703 = 31576756
83 + 31576673 = 31576756
137 + 31576619 = 31576756
173 + 31576583 = 31576756
227 + 31576529 = 31576756

Showing the first eight; more decompositions exist.
