Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550126, here are decompositions:

7 + 31550119 = 31550126
19 + 31550107 = 31550126
79 + 31550047 = 31550126
163 + 31549963 = 31550126
193 + 31549933 = 31550126
229 + 31549897 = 31550126
373 + 31549753 = 31550126
397 + 31549729 = 31550126

Showing the first eight; more decompositions exist.
