Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549704, here are decompositions:

13 + 31549691 = 31549704
37 + 31549667 = 31549704
41 + 31549663 = 31549704
97 + 31549607 = 31549704
107 + 31549597 = 31549704
113 + 31549591 = 31549704
157 + 31549547 = 31549704
293 + 31549411 = 31549704

Showing the first eight; more decompositions exist.
