Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549118, here are decompositions:

19 + 31549099 = 31549118
31 + 31549087 = 31549118
37 + 31549081 = 31549118
67 + 31549051 = 31549118
79 + 31549039 = 31549118
109 + 31549009 = 31549118
157 + 31548961 = 31549118
379 + 31548739 = 31549118

Showing the first eight; more decompositions exist.
