Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12358, here are decompositions:
- 11 + 12347 = 12358
- 29 + 12329 = 12358
- 89 + 12269 = 12358
- 107 + 12251 = 12358
- 131 + 12227 = 12358
- 197 + 12161 = 12358
- 239 + 12119 = 12358
- 251 + 12107 = 12358
Showing the first eight; more decompositions exist.
