Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533664, here are decompositions:
- 3 + 31533661 = 31533664
- 5 + 31533659 = 31533664
- 23 + 31533641 = 31533664
- 53 + 31533611 = 31533664
- 83 + 31533581 = 31533664
- 101 + 31533563 = 31533664
- 131 + 31533533 = 31533664
- 167 + 31533497 = 31533664
Showing the first eight; more decompositions exist.
