Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16656, here are decompositions:

5 + 16651 = 16656
7 + 16649 = 16656
23 + 16633 = 16656
37 + 16619 = 16656
53 + 16603 = 16656
83 + 16573 = 16656
89 + 16567 = 16656
103 + 16553 = 16656

Showing the first eight; more decompositions exist.
