Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16856, here are decompositions:
- 13 + 16843 = 16856
- 97 + 16759 = 16856
- 109 + 16747 = 16856
- 127 + 16729 = 16856
- 157 + 16699 = 16856
- 163 + 16693 = 16856
- 199 + 16657 = 16856
- 223 + 16633 = 16856
Showing the first eight; more decompositions exist.
