Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84216, here are decompositions:
- 5 + 84211 = 84216
- 17 + 84199 = 84216
- 37 + 84179 = 84216
- 53 + 84163 = 84216
- 73 + 84143 = 84216
- 79 + 84137 = 84216
- 89 + 84127 = 84216
- 127 + 84089 = 84216
Showing the first eight; more decompositions exist.
