Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99866, here are decompositions:
- 7 + 99859 = 99866
- 37 + 99829 = 99866
- 43 + 99823 = 99866
- 73 + 99793 = 99866
- 79 + 99787 = 99866
- 157 + 99709 = 99866
- 199 + 99667 = 99866
- 223 + 99643 = 99866
Showing the first eight; more decompositions exist.
