Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67408, here are decompositions:
- 17 + 67391 = 67408
- 59 + 67349 = 67408
- 101 + 67307 = 67408
- 137 + 67271 = 67408
- 191 + 67217 = 67408
- 197 + 67211 = 67408
- 227 + 67181 = 67408
- 239 + 67169 = 67408
Showing the first eight; more decompositions exist.
