Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549214, here are decompositions:

7 + 31549207 = 31549214
13 + 31549201 = 31549214
31 + 31549183 = 31549214
97 + 31549117 = 31549214
127 + 31549087 = 31549214
163 + 31549051 = 31549214
397 + 31548817 = 31549214
457 + 31548757 = 31549214

Showing the first eight; more decompositions exist.
