Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16790, here are decompositions:
- 3 + 16787 = 16790
- 31 + 16759 = 16790
- 43 + 16747 = 16790
- 61 + 16729 = 16790
- 97 + 16693 = 16790
- 139 + 16651 = 16790
- 157 + 16633 = 16790
- 223 + 16567 = 16790
Showing the first eight; more decompositions exist.
