Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543452, here are decompositions:
- 23 + 31543429 = 31543452
- 103 + 31543349 = 31543452
- 151 + 31543301 = 31543452
- 179 + 31543273 = 31543452
- 229 + 31543223 = 31543452
- 233 + 31543219 = 31543452
- 271 + 31543181 = 31543452
- 349 + 31543103 = 31543452
Showing the first eight; more decompositions exist.
