Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7766, here are decompositions:

7 + 7759 = 7766
13 + 7753 = 7766
43 + 7723 = 7766
67 + 7699 = 7766
79 + 7687 = 7766
97 + 7669 = 7766
127 + 7639 = 7766
163 + 7603 = 7766

Showing the first eight; more decompositions exist.
