Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549864, here are decompositions:

83 + 31549781 = 31549864
113 + 31549751 = 31549864
131 + 31549733 = 31549864
173 + 31549691 = 31549864
197 + 31549667 = 31549864
257 + 31549607 = 31549864
317 + 31549547 = 31549864
461 + 31549403 = 31549864

Showing the first eight; more decompositions exist.
