Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550264, here are decompositions:

7 + 31550257 = 31550264
13 + 31550251 = 31550264
43 + 31550221 = 31550264
127 + 31550137 = 31550264
157 + 31550107 = 31550264
283 + 31549981 = 31550264
331 + 31549933 = 31550264
367 + 31549897 = 31550264

Showing the first eight; more decompositions exist.
