Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23380, here are decompositions:
- 11 + 23369 = 23380
- 23 + 23357 = 23380
- 41 + 23339 = 23380
- 47 + 23333 = 23380
- 53 + 23327 = 23380
- 59 + 23321 = 23380
- 83 + 23297 = 23380
- 89 + 23291 = 23380
Showing the first eight; more decompositions exist.
