Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549244, here are decompositions:

3 + 31549241 = 31549244
7 + 31549237 = 31549244
37 + 31549207 = 31549244
43 + 31549201 = 31549244
61 + 31549183 = 31549244
127 + 31549117 = 31549244
157 + 31549087 = 31549244
163 + 31549081 = 31549244

Showing the first eight; more decompositions exist.
