Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533328, here are decompositions:
- 59 + 31533269 = 31533328
- 137 + 31533191 = 31533328
- 179 + 31533149 = 31533328
- 227 + 31533101 = 31533328
- 347 + 31532981 = 31533328
- 389 + 31532939 = 31533328
- 461 + 31532867 = 31533328
- 641 + 31532687 = 31533328
Showing the first eight; more decompositions exist.
