Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9750, here are decompositions:
- 7 + 9743 = 9750
- 11 + 9739 = 9750
- 17 + 9733 = 9750
- 29 + 9721 = 9750
- 31 + 9719 = 9750
- 53 + 9697 = 9750
- 61 + 9689 = 9750
- 71 + 9679 = 9750
Showing the first eight; more decompositions exist.
