Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508676, here are decompositions:

5 + 31508671 = 31508676
19 + 31508657 = 31508676
29 + 31508647 = 31508676
37 + 31508639 = 31508676
97 + 31508579 = 31508676
107 + 31508569 = 31508676
109 + 31508567 = 31508676
127 + 31508549 = 31508676

Showing the first eight; more decompositions exist.
