Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84388, here are decompositions:
- 11 + 84377 = 84388
- 41 + 84347 = 84388
- 71 + 84317 = 84388
- 89 + 84299 = 84388
- 149 + 84239 = 84388
- 167 + 84221 = 84388
- 197 + 84191 = 84388
- 251 + 84137 = 84388
Showing the first eight; more decompositions exist.
