Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16860, here are decompositions:
- 17 + 16843 = 16860
- 29 + 16831 = 16860
- 31 + 16829 = 16860
- 37 + 16823 = 16860
- 73 + 16787 = 16860
- 97 + 16763 = 16860
- 101 + 16759 = 16860
- 113 + 16747 = 16860
Showing the first eight; more decompositions exist.
