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.
