Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549382, here are decompositions:

43 + 31549339 = 31549382
181 + 31549201 = 31549382
199 + 31549183 = 31549382
283 + 31549099 = 31549382
331 + 31549051 = 31549382
373 + 31549009 = 31549382
421 + 31548961 = 31549382
619 + 31548763 = 31549382

Showing the first eight; more decompositions exist.
