Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656690, here are decompositions:

23 + 8656667 = 8656690
101 + 8656589 = 8656690
113 + 8656577 = 8656690
167 + 8656523 = 8656690
173 + 8656517 = 8656690
179 + 8656511 = 8656690
191 + 8656499 = 8656690
197 + 8656493 = 8656690

Showing the first eight; more decompositions exist.
