Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549020, here are decompositions:

11 + 31549009 = 31549020
23 + 31548997 = 31549020
37 + 31548983 = 31549020
59 + 31548961 = 31549020
67 + 31548953 = 31549020
149 + 31548871 = 31549020
163 + 31548857 = 31549020
197 + 31548823 = 31549020

Showing the first eight; more decompositions exist.
