Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9898, here are decompositions:
- 11 + 9887 = 9898
- 41 + 9857 = 9898
- 47 + 9851 = 9898
- 59 + 9839 = 9898
- 107 + 9791 = 9898
- 131 + 9767 = 9898
- 149 + 9749 = 9898
- 179 + 9719 = 9898
Showing the first eight; more decompositions exist.
