Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519796, here are decompositions:

3 + 31519793 = 31519796
13 + 31519783 = 31519796
43 + 31519753 = 31519796
97 + 31519699 = 31519796
109 + 31519687 = 31519796
229 + 31519567 = 31519796
277 + 31519519 = 31519796
313 + 31519483 = 31519796

Showing the first eight; more decompositions exist.
