Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549058, here are decompositions:

7 + 31549051 = 31549058
19 + 31549039 = 31549058
61 + 31548997 = 31549058
97 + 31548961 = 31549058
241 + 31548817 = 31549058
439 + 31548619 = 31549058
631 + 31548427 = 31549058
727 + 31548331 = 31549058

Showing the first eight; more decompositions exist.
