Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549674, here are decompositions:

7 + 31549667 = 31549674
11 + 31549663 = 31549674
67 + 31549607 = 31549674
83 + 31549591 = 31549674
113 + 31549561 = 31549674
127 + 31549547 = 31549674
223 + 31549451 = 31549674
263 + 31549411 = 31549674

Showing the first eight; more decompositions exist.
