Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9816, here are decompositions:
- 5 + 9811 = 9816
- 13 + 9803 = 9816
- 29 + 9787 = 9816
- 47 + 9769 = 9816
- 67 + 9749 = 9816
- 73 + 9743 = 9816
- 83 + 9733 = 9816
- 97 + 9719 = 9816
Showing the first eight; more decompositions exist.
