Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549038, here are decompositions:

19 + 31549019 = 31549038
29 + 31549009 = 31549038
41 + 31548997 = 31549038
167 + 31548871 = 31549038
181 + 31548857 = 31549038
271 + 31548767 = 31549038
281 + 31548757 = 31549038
379 + 31548659 = 31549038

Showing the first eight; more decompositions exist.
