Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549914, here are decompositions:

17 + 31549897 = 31549914
23 + 31549891 = 31549914
41 + 31549873 = 31549914
113 + 31549801 = 31549914
163 + 31549751 = 31549914
181 + 31549733 = 31549914
197 + 31549717 = 31549914
223 + 31549691 = 31549914

Showing the first eight; more decompositions exist.
