Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16808, here are decompositions:

61 + 16747 = 16808
67 + 16741 = 16808
79 + 16729 = 16808
109 + 16699 = 16808
151 + 16657 = 16808
157 + 16651 = 16808
241 + 16567 = 16808
331 + 16477 = 16808

Showing the first eight; more decompositions exist.
