Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549614, here are decompositions:

7 + 31549607 = 31549614
17 + 31549597 = 31549614
23 + 31549591 = 31549614
53 + 31549561 = 31549614
67 + 31549547 = 31549614
163 + 31549451 = 31549614
211 + 31549403 = 31549614
223 + 31549391 = 31549614

Showing the first eight; more decompositions exist.
