Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607698, here are decompositions:

11 + 31607687 = 31607698
167 + 31607531 = 31607698
251 + 31607447 = 31607698
389 + 31607309 = 31607698
401 + 31607297 = 31607698
461 + 31607237 = 31607698
491 + 31607207 = 31607698
659 + 31607039 = 31607698

Showing the first eight; more decompositions exist.
