Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549366, here are decompositions:

29 + 31549337 = 31549366
89 + 31549277 = 31549366
347 + 31549019 = 31549366
383 + 31548983 = 31549366
509 + 31548857 = 31549366
599 + 31548767 = 31549366
617 + 31548749 = 31549366
773 + 31548593 = 31549366

Showing the first eight; more decompositions exist.
