Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576770, here are decompositions:

11 + 31576759 = 31576770
19 + 31576751 = 31576770
31 + 31576739 = 31576770
61 + 31576709 = 31576770
67 + 31576703 = 31576770
89 + 31576681 = 31576770
97 + 31576673 = 31576770
131 + 31576639 = 31576770

Showing the first eight; more decompositions exist.
