Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66670, here are decompositions:
- 17 + 66653 = 66670
- 41 + 66629 = 66670
- 53 + 66617 = 66670
- 83 + 66587 = 66670
- 101 + 66569 = 66670
- 137 + 66533 = 66670
- 179 + 66491 = 66670
- 239 + 66431 = 66670
Showing the first eight; more decompositions exist.
