Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16804, here are decompositions:
- 17 + 16787 = 16804
- 41 + 16763 = 16804
- 101 + 16703 = 16804
- 113 + 16691 = 16804
- 131 + 16673 = 16804
- 173 + 16631 = 16804
- 197 + 16607 = 16804
- 251 + 16553 = 16804
Showing the first eight; more decompositions exist.
