Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550764, here are decompositions:

17 + 31550747 = 31550764
41 + 31550723 = 31550764
53 + 31550711 = 31550764
83 + 31550681 = 31550764
137 + 31550627 = 31550764
191 + 31550573 = 31550764
227 + 31550537 = 31550764
233 + 31550531 = 31550764

Showing the first eight; more decompositions exist.
