Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549422, here are decompositions:

11 + 31549411 = 31549422
19 + 31549403 = 31549422
31 + 31549391 = 31549422
41 + 31549381 = 31549422
83 + 31549339 = 31549422
181 + 31549241 = 31549422
239 + 31549183 = 31549422
241 + 31549181 = 31549422

Showing the first eight; more decompositions exist.
