Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84166, here are decompositions:
- 3 + 84163 = 84166
- 23 + 84143 = 84166
- 29 + 84137 = 84166
- 107 + 84059 = 84166
- 113 + 84053 = 84166
- 149 + 84017 = 84166
- 179 + 83987 = 84166
- 197 + 83969 = 84166
Showing the first eight; more decompositions exist.
