Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549846, here are decompositions:

17 + 31549829 = 31549846
47 + 31549799 = 31549846
113 + 31549733 = 31549846
179 + 31549667 = 31549846
197 + 31549649 = 31549846
239 + 31549607 = 31549846
257 + 31549589 = 31549846
347 + 31549499 = 31549846

Showing the first eight; more decompositions exist.
