Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549584, here are decompositions:

5 + 31549579 = 31549584
23 + 31549561 = 31549584
37 + 31549547 = 31549584
173 + 31549411 = 31549584
181 + 31549403 = 31549584
193 + 31549391 = 31549584
211 + 31549373 = 31549584
257 + 31549327 = 31549584

Showing the first eight; more decompositions exist.
