Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490796, here are decompositions:

17 + 31490779 = 31490796
23 + 31490773 = 31490796
67 + 31490729 = 31490796
83 + 31490713 = 31490796
89 + 31490707 = 31490796
109 + 31490687 = 31490796
137 + 31490659 = 31490796
163 + 31490633 = 31490796

Showing the first eight; more decompositions exist.
