Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550294, here are decompositions:

7 + 31550287 = 31550294
37 + 31550257 = 31550294
43 + 31550251 = 31550294
73 + 31550221 = 31550294
157 + 31550137 = 31550294
163 + 31550131 = 31550294
313 + 31549981 = 31550294
331 + 31549963 = 31550294

Showing the first eight; more decompositions exist.
