Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549414, here are decompositions:

3 + 31549411 = 31549414
11 + 31549403 = 31549414
23 + 31549391 = 31549414
41 + 31549373 = 31549414
137 + 31549277 = 31549414
173 + 31549241 = 31549414
233 + 31549181 = 31549414
431 + 31548983 = 31549414

Showing the first eight; more decompositions exist.
