Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64390, here are decompositions:
- 17 + 64373 = 64390
- 71 + 64319 = 64390
- 89 + 64301 = 64390
- 107 + 64283 = 64390
- 167 + 64223 = 64390
- 173 + 64217 = 64390
- 233 + 64157 = 64390
- 239 + 64151 = 64390
Showing the first eight; more decompositions exist.
