Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16766, here are decompositions:

3 + 16763 = 16766
7 + 16759 = 16766
19 + 16747 = 16766
37 + 16729 = 16766
67 + 16699 = 16766
73 + 16693 = 16766
109 + 16657 = 16766
163 + 16603 = 16766

Showing the first eight; more decompositions exist.
