Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66630, here are decompositions:
- 13 + 66617 = 66630
- 29 + 66601 = 66630
- 37 + 66593 = 66630
- 43 + 66587 = 66630
- 59 + 66571 = 66630
- 61 + 66569 = 66630
- 89 + 66541 = 66630
- 97 + 66533 = 66630
Showing the first eight; more decompositions exist.
