Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549122, here are decompositions:

5 + 31549117 = 31549122
23 + 31549099 = 31549122
41 + 31549081 = 31549122
71 + 31549051 = 31549122
79 + 31549043 = 31549122
83 + 31549039 = 31549122
103 + 31549019 = 31549122
113 + 31549009 = 31549122

Showing the first eight; more decompositions exist.
