Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549616, here are decompositions:

19 + 31549597 = 31549616
37 + 31549579 = 31549616
277 + 31549339 = 31549616
379 + 31549237 = 31549616
409 + 31549207 = 31549616
433 + 31549183 = 31549616
499 + 31549117 = 31549616
577 + 31549039 = 31549616

Showing the first eight; more decompositions exist.
