Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549444, here are decompositions:

5 + 31549439 = 31549444
41 + 31549403 = 31549444
53 + 31549391 = 31549444
71 + 31549373 = 31549444
107 + 31549337 = 31549444
167 + 31549277 = 31549444
263 + 31549181 = 31549444
401 + 31549043 = 31549444

Showing the first eight; more decompositions exist.
