Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549676, here are decompositions:

13 + 31549663 = 31549676
79 + 31549597 = 31549676
97 + 31549579 = 31549676
337 + 31549339 = 31549676
349 + 31549327 = 31549676
439 + 31549237 = 31549676
577 + 31549099 = 31549676
853 + 31548823 = 31549676

Showing the first eight; more decompositions exist.
