Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9918, here are decompositions:
- 11 + 9907 = 9918
- 17 + 9901 = 9918
- 31 + 9887 = 9918
- 47 + 9871 = 9918
- 59 + 9859 = 9918
- 61 + 9857 = 9918
- 67 + 9851 = 9918
- 79 + 9839 = 9918
Showing the first eight; more decompositions exist.
