Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64672, here are decompositions:
- 5 + 64667 = 64672
- 11 + 64661 = 64672
- 59 + 64613 = 64672
- 71 + 64601 = 64672
- 173 + 64499 = 64672
- 233 + 64439 = 64672
- 239 + 64433 = 64672
- 269 + 64403 = 64672
Showing the first eight; more decompositions exist.
