Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549134, here are decompositions:

17 + 31549117 = 31549134
47 + 31549087 = 31549134
53 + 31549081 = 31549134
83 + 31549051 = 31549134
137 + 31548997 = 31549134
151 + 31548983 = 31549134
173 + 31548961 = 31549134
181 + 31548953 = 31549134

Showing the first eight; more decompositions exist.
