Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533730, here are decompositions:
- 23 + 31533707 = 31533730
- 71 + 31533659 = 31533730
- 89 + 31533641 = 31533730
- 131 + 31533599 = 31533730
- 149 + 31533581 = 31533730
- 167 + 31533563 = 31533730
- 197 + 31533533 = 31533730
- 233 + 31533497 = 31533730
Showing the first eight; more decompositions exist.
