Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27868, here are decompositions:
- 17 + 27851 = 27868
- 41 + 27827 = 27868
- 59 + 27809 = 27868
- 89 + 27779 = 27868
- 101 + 27767 = 27868
- 131 + 27737 = 27868
- 167 + 27701 = 27868
- 179 + 27689 = 27868
Showing the first eight; more decompositions exist.
