Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508334, here are decompositions:

5 + 31508329 = 31508334
23 + 31508311 = 31508334
47 + 31508287 = 31508334
101 + 31508233 = 31508334
103 + 31508231 = 31508334
107 + 31508227 = 31508334
131 + 31508203 = 31508334
157 + 31508177 = 31508334

Showing the first eight; more decompositions exist.
