Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549044, here are decompositions:

5 + 31549039 = 31549044
47 + 31548997 = 31549044
61 + 31548983 = 31549044
83 + 31548961 = 31549044
173 + 31548871 = 31549044
227 + 31548817 = 31549044
277 + 31548767 = 31549044
281 + 31548763 = 31549044

Showing the first eight; more decompositions exist.
