Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9786, here are decompositions:

5 + 9781 = 9786
17 + 9769 = 9786
19 + 9767 = 9786
37 + 9749 = 9786
43 + 9743 = 9786
47 + 9739 = 9786
53 + 9733 = 9786
67 + 9719 = 9786

Showing the first eight; more decompositions exist.
