Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533710, here are decompositions:
- 3 + 31533707 = 31533710
- 73 + 31533637 = 31533710
- 79 + 31533631 = 31533710
- 97 + 31533613 = 31533710
- 139 + 31533571 = 31533710
- 163 + 31533547 = 31533710
- 193 + 31533517 = 31533710
- 199 + 31533511 = 31533710
Showing the first eight; more decompositions exist.
