Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549976, here are decompositions:

13 + 31549963 = 31549976
43 + 31549933 = 31549976
79 + 31549897 = 31549976
97 + 31549879 = 31549976
103 + 31549873 = 31549976
223 + 31549753 = 31549976
313 + 31549663 = 31549976
379 + 31549597 = 31549976

Showing the first eight; more decompositions exist.
