Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608676, here are decompositions:

89 + 31608587 = 31608676
149 + 31608527 = 31608676
179 + 31608497 = 31608676
227 + 31608449 = 31608676
509 + 31608167 = 31608676
569 + 31608107 = 31608676
647 + 31608029 = 31608676
773 + 31607903 = 31608676

Showing the first eight; more decompositions exist.
