Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13368, here are decompositions:
- 29 + 13339 = 13368
- 31 + 13337 = 13368
- 37 + 13331 = 13368
- 41 + 13327 = 13368
- 59 + 13309 = 13368
- 71 + 13297 = 13368
- 101 + 13267 = 13368
- 109 + 13259 = 13368
Showing the first eight; more decompositions exist.
