Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 238, here are decompositions:
- 5 + 233 = 238
- 11 + 227 = 238
- 41 + 197 = 238
- 47 + 191 = 238
- 59 + 179 = 238
- 71 + 167 = 238
- 89 + 149 = 238
- 101 + 137 = 238
Showing the first eight; more decompositions exist.
