Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716566, here are decompositions:

13 + 8716553 = 8716566
97 + 8716469 = 8716566
113 + 8716453 = 8716566
127 + 8716439 = 8716566
137 + 8716429 = 8716566
193 + 8716373 = 8716566
277 + 8716289 = 8716566
283 + 8716283 = 8716566

Showing the first eight; more decompositions exist.
