Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533736, here are decompositions:
- 29 + 31533707 = 31533736
- 137 + 31533599 = 31533736
- 149 + 31533587 = 31533736
- 173 + 31533563 = 31533736
- 239 + 31533497 = 31533736
- 347 + 31533389 = 31533736
- 467 + 31533269 = 31533736
- 569 + 31533167 = 31533736
Showing the first eight; more decompositions exist.
