Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550756, here are decompositions:

157 + 31550599 = 31550756
163 + 31550593 = 31550756
199 + 31550557 = 31550756
277 + 31550479 = 31550756
499 + 31550257 = 31550756
577 + 31550179 = 31550756
607 + 31550149 = 31550756
619 + 31550137 = 31550756

Showing the first eight; more decompositions exist.
