Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508734, here are decompositions:

3 + 31508731 = 31508734
53 + 31508681 = 31508734
83 + 31508651 = 31508734
113 + 31508621 = 31508734
167 + 31508567 = 31508734
227 + 31508507 = 31508734
281 + 31508453 = 31508734
317 + 31508417 = 31508734

Showing the first eight; more decompositions exist.
