Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519596, here are decompositions:

13 + 31519583 = 31519596
29 + 31519567 = 31519596
89 + 31519507 = 31519596
109 + 31519487 = 31519596
113 + 31519483 = 31519596
137 + 31519459 = 31519596
139 + 31519457 = 31519596
179 + 31519417 = 31519596

Showing the first eight; more decompositions exist.
