Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549110, here are decompositions:

11 + 31549099 = 31549110
23 + 31549087 = 31549110
29 + 31549081 = 31549110
59 + 31549051 = 31549110
67 + 31549043 = 31549110
71 + 31549039 = 31549110
101 + 31549009 = 31549110
113 + 31548997 = 31549110

Showing the first eight; more decompositions exist.
