Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82216, here are decompositions:
- 23 + 82193 = 82216
- 53 + 82163 = 82216
- 149 + 82067 = 82216
- 179 + 82037 = 82216
- 263 + 81953 = 82216
- 317 + 81899 = 82216
- 347 + 81869 = 82216
- 443 + 81773 = 82216
Showing the first eight; more decompositions exist.
