Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 230, here are decompositions:
- 3 + 227 = 230
- 7 + 223 = 230
- 19 + 211 = 230
- 31 + 199 = 230
- 37 + 193 = 230
- 67 + 163 = 230
- 73 + 157 = 230
- 79 + 151 = 230
Showing the first eight; more decompositions exist.
