Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549112, here are decompositions:

13 + 31549099 = 31549112
31 + 31549081 = 31549112
61 + 31549051 = 31549112
73 + 31549039 = 31549112
103 + 31549009 = 31549112
151 + 31548961 = 31549112
241 + 31548871 = 31549112
349 + 31548763 = 31549112

Showing the first eight; more decompositions exist.
