Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16788, here are decompositions:
- 29 + 16759 = 16788
- 41 + 16747 = 16788
- 47 + 16741 = 16788
- 59 + 16729 = 16788
- 89 + 16699 = 16788
- 97 + 16691 = 16788
- 127 + 16661 = 16788
- 131 + 16657 = 16788
Showing the first eight; more decompositions exist.
