Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16776, here are decompositions:

13 + 16763 = 16776
17 + 16759 = 16776
29 + 16747 = 16776
47 + 16729 = 16776
73 + 16703 = 16776
83 + 16693 = 16776
103 + 16673 = 16776
127 + 16649 = 16776

Showing the first eight; more decompositions exist.
