Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16660, here are decompositions:
- 3 + 16657 = 16660
- 11 + 16649 = 16660
- 29 + 16631 = 16660
- 41 + 16619 = 16660
- 53 + 16607 = 16660
- 107 + 16553 = 16660
- 113 + 16547 = 16660
- 131 + 16529 = 16660
Showing the first eight; more decompositions exist.
