Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9684, here are decompositions:

5 + 9679 = 9684
7 + 9677 = 9684
23 + 9661 = 9684
41 + 9643 = 9684
53 + 9631 = 9684
61 + 9623 = 9684
71 + 9613 = 9684
83 + 9601 = 9684

Showing the first eight; more decompositions exist.
