Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8560, here are decompositions:

17 + 8543 = 8560
23 + 8537 = 8560
47 + 8513 = 8560
59 + 8501 = 8560
113 + 8447 = 8560
131 + 8429 = 8560
137 + 8423 = 8560
173 + 8387 = 8560

Showing the first eight; more decompositions exist.
