Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549546, here are decompositions:

47 + 31549499 = 31549546
107 + 31549439 = 31549546
173 + 31549373 = 31549546
269 + 31549277 = 31549546
503 + 31549043 = 31549546
563 + 31548983 = 31549546
593 + 31548953 = 31549546
797 + 31548749 = 31549546

Showing the first eight; more decompositions exist.
