Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533668, here are decompositions:
- 7 + 31533661 = 31533668
- 31 + 31533637 = 31533668
- 37 + 31533631 = 31533668
- 97 + 31533571 = 31533668
- 151 + 31533517 = 31533668
- 157 + 31533511 = 31533668
- 409 + 31533259 = 31533668
- 541 + 31533127 = 31533668
Showing the first eight; more decompositions exist.
