Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16866, here are decompositions:

23 + 16843 = 16866
37 + 16829 = 16866
43 + 16823 = 16866
79 + 16787 = 16866
103 + 16763 = 16866
107 + 16759 = 16866
137 + 16729 = 16866
163 + 16703 = 16866

Showing the first eight; more decompositions exist.
