Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549232, here are decompositions:

31 + 31549201 = 31549232
151 + 31549081 = 31549232
181 + 31549051 = 31549232
193 + 31549039 = 31549232
223 + 31549009 = 31549232
271 + 31548961 = 31549232
409 + 31548823 = 31549232
499 + 31548733 = 31549232

Showing the first eight; more decompositions exist.
