Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549536, here are decompositions:

37 + 31549499 = 31549536
97 + 31549439 = 31549536
163 + 31549373 = 31549536
197 + 31549339 = 31549536
199 + 31549337 = 31549536
353 + 31549183 = 31549536
419 + 31549117 = 31549536
449 + 31549087 = 31549536

Showing the first eight; more decompositions exist.
