Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533654, here are decompositions:
- 13 + 31533641 = 31533654
- 17 + 31533637 = 31533654
- 23 + 31533631 = 31533654
- 41 + 31533613 = 31533654
- 43 + 31533611 = 31533654
- 67 + 31533587 = 31533654
- 73 + 31533581 = 31533654
- 83 + 31533571 = 31533654
Showing the first eight; more decompositions exist.
