Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549208, here are decompositions:

7 + 31549201 = 31549208
109 + 31549099 = 31549208
127 + 31549081 = 31549208
157 + 31549051 = 31549208
199 + 31549009 = 31549208
211 + 31548997 = 31549208
337 + 31548871 = 31549208
631 + 31548577 = 31549208

Showing the first eight; more decompositions exist.
