Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549224, here are decompositions:

17 + 31549207 = 31549224
23 + 31549201 = 31549224
41 + 31549183 = 31549224
43 + 31549181 = 31549224
107 + 31549117 = 31549224
137 + 31549087 = 31549224
173 + 31549051 = 31549224
181 + 31549043 = 31549224

Showing the first eight; more decompositions exist.
