Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64384, here are decompositions:
- 3 + 64381 = 64384
- 11 + 64373 = 64384
- 83 + 64301 = 64384
- 101 + 64283 = 64384
- 113 + 64271 = 64384
- 167 + 64217 = 64384
- 197 + 64187 = 64384
- 227 + 64157 = 64384
Showing the first eight; more decompositions exist.
