Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510696, here are decompositions:

5 + 31510691 = 31510696
17 + 31510679 = 31510696
179 + 31510517 = 31510696
263 + 31510433 = 31510696
293 + 31510403 = 31510696
479 + 31510217 = 31510696
509 + 31510187 = 31510696
557 + 31510139 = 31510696

Showing the first eight; more decompositions exist.
