Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40678, here are decompositions:
- 41 + 40637 = 40678
- 101 + 40577 = 40678
- 149 + 40529 = 40678
- 179 + 40499 = 40678
- 191 + 40487 = 40678
- 251 + 40427 = 40678
- 317 + 40361 = 40678
- 389 + 40289 = 40678
Showing the first eight; more decompositions exist.
