Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9928, here are decompositions:
- 5 + 9923 = 9928
- 41 + 9887 = 9928
- 71 + 9857 = 9928
- 89 + 9839 = 9928
- 137 + 9791 = 9928
- 179 + 9749 = 9928
- 239 + 9689 = 9928
- 251 + 9677 = 9928
Showing the first eight; more decompositions exist.
