Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16810, here are decompositions:
- 23 + 16787 = 16810
- 47 + 16763 = 16810
- 107 + 16703 = 16810
- 137 + 16673 = 16810
- 149 + 16661 = 16810
- 179 + 16631 = 16810
- 191 + 16619 = 16810
- 257 + 16553 = 16810
Showing the first eight; more decompositions exist.
