Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549654, here are decompositions:

5 + 31549649 = 31549654
47 + 31549607 = 31549654
107 + 31549547 = 31549654
251 + 31549403 = 31549654
263 + 31549391 = 31549654
281 + 31549373 = 31549654
317 + 31549337 = 31549654
701 + 31548953 = 31549654

Showing the first eight; more decompositions exist.
