Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549450, here are decompositions:

11 + 31549439 = 31549450
47 + 31549403 = 31549450
59 + 31549391 = 31549450
113 + 31549337 = 31549450
173 + 31549277 = 31549450
269 + 31549181 = 31549450
431 + 31549019 = 31549450
467 + 31548983 = 31549450

Showing the first eight; more decompositions exist.
