Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9780, here are decompositions:

11 + 9769 = 9780
13 + 9767 = 9780
31 + 9749 = 9780
37 + 9743 = 9780
41 + 9739 = 9780
47 + 9733 = 9780
59 + 9721 = 9780
61 + 9719 = 9780

Showing the first eight; more decompositions exist.
