Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549626, here are decompositions:

19 + 31549607 = 31549626
29 + 31549597 = 31549626
37 + 31549589 = 31549626
47 + 31549579 = 31549626
79 + 31549547 = 31549626
127 + 31549499 = 31549626
223 + 31549403 = 31549626
349 + 31549277 = 31549626

Showing the first eight; more decompositions exist.
