Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576762, here are decompositions:

3 + 31576759 = 31576762
11 + 31576751 = 31576762
23 + 31576739 = 31576762
53 + 31576709 = 31576762
59 + 31576703 = 31576762
89 + 31576673 = 31576762
179 + 31576583 = 31576762
233 + 31576529 = 31576762

Showing the first eight; more decompositions exist.
