Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6806, here are decompositions:
- 3 + 6803 = 6806
- 13 + 6793 = 6806
- 43 + 6763 = 6806
- 73 + 6733 = 6806
- 97 + 6709 = 6806
- 103 + 6703 = 6806
- 127 + 6679 = 6806
- 199 + 6607 = 6806
Showing the first eight; more decompositions exist.
