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.
