Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13338, here are decompositions:
- 7 + 13331 = 13338
- 11 + 13327 = 13338
- 29 + 13309 = 13338
- 41 + 13297 = 13338
- 47 + 13291 = 13338
- 71 + 13267 = 13338
- 79 + 13259 = 13338
- 89 + 13249 = 13338
Showing the first eight; more decompositions exist.
