Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13320, here are decompositions:
- 7 + 13313 = 13320
- 11 + 13309 = 13320
- 23 + 13297 = 13320
- 29 + 13291 = 13320
- 53 + 13267 = 13320
- 61 + 13259 = 13320
- 71 + 13249 = 13320
- 79 + 13241 = 13320
Showing the first eight; more decompositions exist.
