Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536384, here are decompositions:
- 23 + 31536361 = 31536384
- 31 + 31536353 = 31536384
- 37 + 31536347 = 31536384
- 71 + 31536313 = 31536384
- 97 + 31536287 = 31536384
- 157 + 31536227 = 31536384
- 181 + 31536203 = 31536384
- 197 + 31536187 = 31536384
Showing the first eight; more decompositions exist.
