Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82168, here are decompositions:
- 5 + 82163 = 82168
- 29 + 82139 = 82168
- 101 + 82067 = 82168
- 131 + 82037 = 82168
- 137 + 82031 = 82168
- 197 + 81971 = 82168
- 239 + 81929 = 82168
- 269 + 81899 = 82168
Showing the first eight; more decompositions exist.
