Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82166, here are decompositions:
- 3 + 82163 = 82166
- 13 + 82153 = 82166
- 37 + 82129 = 82166
- 127 + 82039 = 82166
- 157 + 82009 = 82166
- 163 + 82003 = 82166
- 193 + 81973 = 82166
- 199 + 81967 = 82166
Showing the first eight; more decompositions exist.
