Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83856, here are decompositions:
- 13 + 83843 = 83856
- 23 + 83833 = 83856
- 43 + 83813 = 83856
- 79 + 83777 = 83856
- 83 + 83773 = 83856
- 137 + 83719 = 83856
- 139 + 83717 = 83856
- 167 + 83689 = 83856
Showing the first eight; more decompositions exist.
