Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27856, here are decompositions:
- 5 + 27851 = 27856
- 29 + 27827 = 27856
- 47 + 27809 = 27856
- 53 + 27803 = 27856
- 83 + 27773 = 27856
- 89 + 27767 = 27856
- 107 + 27749 = 27856
- 113 + 27743 = 27856
Showing the first eight; more decompositions exist.
