Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671690, here are decompositions:

59 + 8671631 = 8671690
101 + 8671589 = 8671690
107 + 8671583 = 8671690
173 + 8671517 = 8671690
179 + 8671511 = 8671690
191 + 8671499 = 8671690
227 + 8671463 = 8671690
233 + 8671457 = 8671690

Showing the first eight; more decompositions exist.
