Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 250, here are decompositions:
- 11 + 239 = 250
- 17 + 233 = 250
- 23 + 227 = 250
- 53 + 197 = 250
- 59 + 191 = 250
- 71 + 179 = 250
- 83 + 167 = 250
- 101 + 149 = 250
Showing the first eight; more decompositions exist.
