Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9648, here are decompositions:
- 5 + 9643 = 9648
- 17 + 9631 = 9648
- 19 + 9629 = 9648
- 29 + 9619 = 9648
- 47 + 9601 = 9648
- 61 + 9587 = 9648
- 97 + 9551 = 9648
- 101 + 9547 = 9648
Showing the first eight; more decompositions exist.
