Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40384, here are decompositions:
- 23 + 40361 = 40384
- 41 + 40343 = 40384
- 101 + 40283 = 40384
- 107 + 40277 = 40384
- 131 + 40253 = 40384
- 191 + 40193 = 40384
- 233 + 40151 = 40384
- 257 + 40127 = 40384
Showing the first eight; more decompositions exist.
