Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16728, here are decompositions:
- 29 + 16699 = 16728
- 37 + 16691 = 16728
- 67 + 16661 = 16728
- 71 + 16657 = 16728
- 79 + 16649 = 16728
- 97 + 16631 = 16728
- 109 + 16619 = 16728
- 167 + 16561 = 16728
Showing the first eight; more decompositions exist.
