Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508682, here are decompositions:

5 + 31508677 = 31508682
11 + 31508671 = 31508682
31 + 31508651 = 31508682
43 + 31508639 = 31508682
61 + 31508621 = 31508682
103 + 31508579 = 31508682
113 + 31508569 = 31508682
173 + 31508509 = 31508682

Showing the first eight; more decompositions exist.
