Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550634, here are decompositions:

7 + 31550627 = 31550634
23 + 31550611 = 31550634
41 + 31550593 = 31550634
47 + 31550587 = 31550634
53 + 31550581 = 31550634
61 + 31550573 = 31550634
97 + 31550537 = 31550634
103 + 31550531 = 31550634

Showing the first eight; more decompositions exist.
