Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549164, here are decompositions:

47 + 31549117 = 31549164
83 + 31549081 = 31549164
113 + 31549051 = 31549164
167 + 31548997 = 31549164
181 + 31548983 = 31549164
211 + 31548953 = 31549164
293 + 31548871 = 31549164
307 + 31548857 = 31549164

Showing the first eight; more decompositions exist.
