Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550682, here are decompositions:

11 + 31550671 = 31550682
71 + 31550611 = 31550682
83 + 31550599 = 31550682
89 + 31550593 = 31550682
101 + 31550581 = 31550682
109 + 31550573 = 31550682
113 + 31550569 = 31550682
139 + 31550543 = 31550682

Showing the first eight; more decompositions exist.
