Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596770, here are decompositions:

13 + 31596757 = 31596770
19 + 31596751 = 31596770
61 + 31596709 = 31596770
97 + 31596673 = 31596770
109 + 31596661 = 31596770
157 + 31596613 = 31596770
199 + 31596571 = 31596770
229 + 31596541 = 31596770

Showing the first eight; more decompositions exist.
