Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549328, here are decompositions:

127 + 31549201 = 31549328
211 + 31549117 = 31549328
229 + 31549099 = 31549328
241 + 31549087 = 31549328
277 + 31549051 = 31549328
331 + 31548997 = 31549328
367 + 31548961 = 31549328
457 + 31548871 = 31549328

Showing the first eight; more decompositions exist.
