Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9786, here are decompositions:
- 5 + 9781 = 9786
- 17 + 9769 = 9786
- 19 + 9767 = 9786
- 37 + 9749 = 9786
- 43 + 9743 = 9786
- 47 + 9739 = 9786
- 53 + 9733 = 9786
- 67 + 9719 = 9786
Showing the first eight; more decompositions exist.
