Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550670, here are decompositions:

43 + 31550627 = 31550670
59 + 31550611 = 31550670
71 + 31550599 = 31550670
83 + 31550587 = 31550670
89 + 31550581 = 31550670
97 + 31550573 = 31550670
101 + 31550569 = 31550670
113 + 31550557 = 31550670

Showing the first eight; more decompositions exist.
