Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549344, here are decompositions:

5 + 31549339 = 31549344
7 + 31549337 = 31549344
17 + 31549327 = 31549344
67 + 31549277 = 31549344
103 + 31549241 = 31549344
107 + 31549237 = 31549344
137 + 31549207 = 31549344
163 + 31549181 = 31549344

Showing the first eight; more decompositions exist.
