Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16740, here are decompositions:
- 11 + 16729 = 16740
- 37 + 16703 = 16740
- 41 + 16699 = 16740
- 47 + 16693 = 16740
- 67 + 16673 = 16740
- 79 + 16661 = 16740
- 83 + 16657 = 16740
- 89 + 16651 = 16740
Showing the first eight; more decompositions exist.
