Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533306, here are decompositions:
- 37 + 31533269 = 31533306
- 47 + 31533259 = 31533306
- 97 + 31533209 = 31533306
- 139 + 31533167 = 31533306
- 157 + 31533149 = 31533306
- 163 + 31533143 = 31533306
- 173 + 31533133 = 31533306
- 179 + 31533127 = 31533306
Showing the first eight; more decompositions exist.
