Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549358, here are decompositions:

19 + 31549339 = 31549358
31 + 31549327 = 31549358
151 + 31549207 = 31549358
157 + 31549201 = 31549358
241 + 31549117 = 31549358
271 + 31549087 = 31549358
277 + 31549081 = 31549358
307 + 31549051 = 31549358

Showing the first eight; more decompositions exist.
