Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16768, here are decompositions:
- 5 + 16763 = 16768
- 107 + 16661 = 16768
- 137 + 16631 = 16768
- 149 + 16619 = 16768
- 239 + 16529 = 16768
- 281 + 16487 = 16768
- 317 + 16451 = 16768
- 347 + 16421 = 16768
Showing the first eight; more decompositions exist.
