Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66600, here are decompositions:
- 7 + 66593 = 66600
- 13 + 66587 = 66600
- 29 + 66571 = 66600
- 31 + 66569 = 66600
- 47 + 66553 = 66600
- 59 + 66541 = 66600
- 67 + 66533 = 66600
- 71 + 66529 = 66600
Showing the first eight; more decompositions exist.
