Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16678, here are decompositions:
- 5 + 16673 = 16678
- 17 + 16661 = 16678
- 29 + 16649 = 16678
- 47 + 16631 = 16678
- 59 + 16619 = 16678
- 71 + 16607 = 16678
- 131 + 16547 = 16678
- 149 + 16529 = 16678
Showing the first eight; more decompositions exist.
