Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549946, here are decompositions:

13 + 31549933 = 31549946
67 + 31549879 = 31549946
73 + 31549873 = 31549946
193 + 31549753 = 31549946
229 + 31549717 = 31549946
283 + 31549663 = 31549946
349 + 31549597 = 31549946
367 + 31549579 = 31549946

Showing the first eight; more decompositions exist.
