Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 234, here are decompositions:
- 5 + 229 = 234
- 7 + 227 = 234
- 11 + 223 = 234
- 23 + 211 = 234
- 37 + 197 = 234
- 41 + 193 = 234
- 43 + 191 = 234
- 53 + 181 = 234
Showing the first eight; more decompositions exist.
