Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533354, here are decompositions:
- 11 + 31533343 = 31533354
- 163 + 31533191 = 31533354
- 211 + 31533143 = 31533354
- 227 + 31533127 = 31533354
- 257 + 31533097 = 31533354
- 263 + 31533091 = 31533354
- 353 + 31533001 = 31533354
- 373 + 31532981 = 31533354
Showing the first eight; more decompositions exist.
