Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549036, here are decompositions:

17 + 31549019 = 31549036
53 + 31548983 = 31549036
83 + 31548953 = 31549036
179 + 31548857 = 31549036
269 + 31548767 = 31549036
293 + 31548743 = 31549036
359 + 31548677 = 31549036
383 + 31548653 = 31549036

Showing the first eight; more decompositions exist.
