Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16786, here are decompositions:
- 23 + 16763 = 16786
- 83 + 16703 = 16786
- 113 + 16673 = 16786
- 137 + 16649 = 16786
- 167 + 16619 = 16786
- 179 + 16607 = 16786
- 233 + 16553 = 16786
- 239 + 16547 = 16786
Showing the first eight; more decompositions exist.
