Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23258, here are decompositions:
- 7 + 23251 = 23258
- 31 + 23227 = 23258
- 61 + 23197 = 23258
- 127 + 23131 = 23258
- 199 + 23059 = 23258
- 229 + 23029 = 23258
- 241 + 23017 = 23258
- 337 + 22921 = 23258
Showing the first eight; more decompositions exist.
