Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 252, here are decompositions:
- 11 + 241 = 252
- 13 + 239 = 252
- 19 + 233 = 252
- 23 + 229 = 252
- 29 + 223 = 252
- 41 + 211 = 252
- 53 + 199 = 252
- 59 + 193 = 252
Showing the first eight; more decompositions exist.
