Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84208, here are decompositions:
- 17 + 84191 = 84208
- 29 + 84179 = 84208
- 71 + 84137 = 84208
- 149 + 84059 = 84208
- 191 + 84017 = 84208
- 197 + 84011 = 84208
- 239 + 83969 = 84208
- 269 + 83939 = 84208
Showing the first eight; more decompositions exist.
