Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543446, here are decompositions:
- 17 + 31543429 = 31543446
- 97 + 31543349 = 31543446
- 173 + 31543273 = 31543446
- 223 + 31543223 = 31543446
- 227 + 31543219 = 31543446
- 229 + 31543217 = 31543446
- 239 + 31543207 = 31543446
- 283 + 31543163 = 31543446
Showing the first eight; more decompositions exist.
