Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508846, here are decompositions:

3 + 31508843 = 31508846
163 + 31508683 = 31508846
199 + 31508647 = 31508846
277 + 31508569 = 31508846
337 + 31508509 = 31508846
487 + 31508359 = 31508846
613 + 31508233 = 31508846
619 + 31508227 = 31508846

Showing the first eight; more decompositions exist.
