Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66828, here are decompositions:
- 7 + 66821 = 66828
- 19 + 66809 = 66828
- 31 + 66797 = 66828
- 37 + 66791 = 66828
- 79 + 66749 = 66828
- 89 + 66739 = 66828
- 107 + 66721 = 66828
- 127 + 66701 = 66828
Showing the first eight; more decompositions exist.
