Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8566, here are decompositions:

3 + 8563 = 8566
23 + 8543 = 8566
29 + 8537 = 8566
53 + 8513 = 8566
137 + 8429 = 8566
179 + 8387 = 8566
197 + 8369 = 8566
269 + 8297 = 8566

Showing the first eight; more decompositions exist.
