Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84168, here are decompositions:
- 5 + 84163 = 84168
- 31 + 84137 = 84168
- 37 + 84131 = 84168
- 41 + 84127 = 84168
- 47 + 84121 = 84168
- 79 + 84089 = 84168
- 101 + 84067 = 84168
- 107 + 84061 = 84168
Showing the first eight; more decompositions exist.
