Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549054, here are decompositions:

3 + 31549051 = 31549054
11 + 31549043 = 31549054
71 + 31548983 = 31549054
101 + 31548953 = 31549054
197 + 31548857 = 31549054
311 + 31548743 = 31549054
401 + 31548653 = 31549054
461 + 31548593 = 31549054

Showing the first eight; more decompositions exist.
