Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549362, here are decompositions:

23 + 31549339 = 31549362
179 + 31549183 = 31549362
181 + 31549181 = 31549362
263 + 31549099 = 31549362
281 + 31549081 = 31549362
311 + 31549051 = 31549362
353 + 31549009 = 31549362
379 + 31548983 = 31549362

Showing the first eight; more decompositions exist.
