Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13384, here are decompositions:
- 3 + 13381 = 13384
- 17 + 13367 = 13384
- 47 + 13337 = 13384
- 53 + 13331 = 13384
- 71 + 13313 = 13384
- 167 + 13217 = 13384
- 197 + 13187 = 13384
- 233 + 13151 = 13384
Showing the first eight; more decompositions exist.
