Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13386, here are decompositions:
- 5 + 13381 = 13386
- 19 + 13367 = 13386
- 47 + 13339 = 13386
- 59 + 13327 = 13386
- 73 + 13313 = 13386
- 89 + 13297 = 13386
- 127 + 13259 = 13386
- 137 + 13249 = 13386
Showing the first eight; more decompositions exist.
