Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9666, here are decompositions:
- 5 + 9661 = 9666
- 17 + 9649 = 9666
- 23 + 9643 = 9666
- 37 + 9629 = 9666
- 43 + 9623 = 9666
- 47 + 9619 = 9666
- 53 + 9613 = 9666
- 79 + 9587 = 9666
Showing the first eight; more decompositions exist.
