Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533824, here are decompositions:
- 61 + 31533763 = 31533824
- 103 + 31533721 = 31533824
- 163 + 31533661 = 31533824
- 193 + 31533631 = 31533824
- 211 + 31533613 = 31533824
- 277 + 31533547 = 31533824
- 307 + 31533517 = 31533824
- 313 + 31533511 = 31533824
Showing the first eight; more decompositions exist.
