Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549012, here are decompositions:

3 + 31549009 = 31549012
29 + 31548983 = 31549012
59 + 31548953 = 31549012
263 + 31548749 = 31549012
269 + 31548743 = 31549012
353 + 31548659 = 31549012
359 + 31548653 = 31549012
419 + 31548593 = 31549012

Showing the first eight; more decompositions exist.
