Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9778, here are decompositions:

11 + 9767 = 9778
29 + 9749 = 9778
59 + 9719 = 9778
89 + 9689 = 9778
101 + 9677 = 9778
149 + 9629 = 9778
191 + 9587 = 9778
227 + 9551 = 9778

Showing the first eight; more decompositions exist.
