Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525916, here are decompositions:
- 3 + 31525913 = 31525916
- 7 + 31525909 = 31525916
- 13 + 31525903 = 31525916
- 67 + 31525849 = 31525916
- 139 + 31525777 = 31525916
- 193 + 31525723 = 31525916
- 199 + 31525717 = 31525916
- 229 + 31525687 = 31525916
Showing the first eight; more decompositions exist.
