Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519766, here are decompositions:

13 + 31519753 = 31519766
67 + 31519699 = 31519766
79 + 31519687 = 31519766
199 + 31519567 = 31519766
283 + 31519483 = 31519766
307 + 31519459 = 31519766
349 + 31519417 = 31519766
409 + 31519357 = 31519766

Showing the first eight; more decompositions exist.
