Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549104, here are decompositions:

5 + 31549099 = 31549104
17 + 31549087 = 31549104
23 + 31549081 = 31549104
53 + 31549051 = 31549104
61 + 31549043 = 31549104
107 + 31548997 = 31549104
151 + 31548953 = 31549104
233 + 31548871 = 31549104

Showing the first eight; more decompositions exist.
