Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16806, here are decompositions:

19 + 16787 = 16806
43 + 16763 = 16806
47 + 16759 = 16806
59 + 16747 = 16806
103 + 16703 = 16806
107 + 16699 = 16806
113 + 16693 = 16806
149 + 16657 = 16806

Showing the first eight; more decompositions exist.
