Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9790, here are decompositions:

3 + 9787 = 9790
23 + 9767 = 9790
41 + 9749 = 9790
47 + 9743 = 9790
71 + 9719 = 9790
101 + 9689 = 9790
113 + 9677 = 9790
167 + 9623 = 9790

Showing the first eight; more decompositions exist.
