Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533330, here are decompositions:
- 61 + 31533269 = 31533330
- 71 + 31533259 = 31533330
- 139 + 31533191 = 31533330
- 163 + 31533167 = 31533330
- 181 + 31533149 = 31533330
- 197 + 31533133 = 31533330
- 211 + 31533119 = 31533330
- 229 + 31533101 = 31533330
Showing the first eight; more decompositions exist.
