Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6816, here are decompositions:
- 13 + 6803 = 6816
- 23 + 6793 = 6816
- 37 + 6779 = 6816
- 53 + 6763 = 6816
- 79 + 6737 = 6816
- 83 + 6733 = 6816
- 97 + 6719 = 6816
- 107 + 6709 = 6816
Showing the first eight; more decompositions exist.
