Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9916, here are decompositions:
- 29 + 9887 = 9916
- 59 + 9857 = 9916
- 83 + 9833 = 9916
- 113 + 9803 = 9916
- 149 + 9767 = 9916
- 167 + 9749 = 9916
- 173 + 9743 = 9916
- 197 + 9719 = 9916
Showing the first eight; more decompositions exist.
