Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99810, here are decompositions:
- 17 + 99793 = 99810
- 23 + 99787 = 99810
- 43 + 99767 = 99810
- 89 + 99721 = 99810
- 97 + 99713 = 99810
- 101 + 99709 = 99810
- 103 + 99707 = 99810
- 131 + 99679 = 99810
Showing the first eight; more decompositions exist.
