Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549046, here are decompositions:

3 + 31549043 = 31549046
7 + 31549039 = 31549046
37 + 31549009 = 31549046
223 + 31548823 = 31549046
229 + 31548817 = 31549046
283 + 31548763 = 31549046
307 + 31548739 = 31549046
313 + 31548733 = 31549046

Showing the first eight; more decompositions exist.
