Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549822, here are decompositions:

23 + 31549799 = 31549822
41 + 31549781 = 31549822
71 + 31549751 = 31549822
89 + 31549733 = 31549822
131 + 31549691 = 31549822
173 + 31549649 = 31549822
233 + 31549589 = 31549822
383 + 31549439 = 31549822

Showing the first eight; more decompositions exist.
