Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549082, here are decompositions:

31 + 31549051 = 31549082
43 + 31549039 = 31549082
73 + 31549009 = 31549082
211 + 31548871 = 31549082
349 + 31548733 = 31549082
463 + 31548619 = 31549082
739 + 31548343 = 31549082
751 + 31548331 = 31549082

Showing the first eight; more decompositions exist.
