Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16828, here are decompositions:
- 5 + 16823 = 16828
- 17 + 16811 = 16828
- 41 + 16787 = 16828
- 137 + 16691 = 16828
- 167 + 16661 = 16828
- 179 + 16649 = 16828
- 197 + 16631 = 16828
- 281 + 16547 = 16828
Showing the first eight; more decompositions exist.
