Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9766, here are decompositions:

17 + 9749 = 9766
23 + 9743 = 9766
47 + 9719 = 9766
89 + 9677 = 9766
137 + 9629 = 9766
179 + 9587 = 9766
227 + 9539 = 9766
233 + 9533 = 9766

Showing the first eight; more decompositions exist.
