Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549794, here are decompositions:

13 + 31549781 = 31549794
41 + 31549753 = 31549794
43 + 31549751 = 31549794
61 + 31549733 = 31549794
103 + 31549691 = 31549794
127 + 31549667 = 31549794
131 + 31549663 = 31549794
197 + 31549597 = 31549794

Showing the first eight; more decompositions exist.
