Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550270, here are decompositions:

13 + 31550257 = 31550270
19 + 31550251 = 31550270
139 + 31550131 = 31550270
151 + 31550119 = 31550270
163 + 31550107 = 31550270
223 + 31550047 = 31550270
307 + 31549963 = 31550270
337 + 31549933 = 31550270

Showing the first eight; more decompositions exist.
