Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16728, here are decompositions:

29 + 16699 = 16728
37 + 16691 = 16728
67 + 16661 = 16728
71 + 16657 = 16728
79 + 16649 = 16728
97 + 16631 = 16728
109 + 16619 = 16728
167 + 16561 = 16728

Showing the first eight; more decompositions exist.
