Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66700, here are decompositions:
- 3 + 66697 = 66700
- 17 + 66683 = 66700
- 47 + 66653 = 66700
- 71 + 66629 = 66700
- 83 + 66617 = 66700
- 107 + 66593 = 66700
- 113 + 66587 = 66700
- 131 + 66569 = 66700
Showing the first eight; more decompositions exist.
