Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9966, here are decompositions:
- 17 + 9949 = 9966
- 37 + 9929 = 9966
- 43 + 9923 = 9966
- 59 + 9907 = 9966
- 79 + 9887 = 9966
- 83 + 9883 = 9966
- 107 + 9859 = 9966
- 109 + 9857 = 9966
Showing the first eight; more decompositions exist.
