Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508634, here are decompositions:

13 + 31508621 = 31508634
67 + 31508567 = 31508634
107 + 31508527 = 31508634
127 + 31508507 = 31508634
173 + 31508461 = 31508634
181 + 31508453 = 31508634
191 + 31508443 = 31508634
271 + 31508363 = 31508634

Showing the first eight; more decompositions exist.
