Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525898, here are decompositions:
- 7 + 31525891 = 31525898
- 127 + 31525771 = 31525898
- 181 + 31525717 = 31525898
- 199 + 31525699 = 31525898
- 211 + 31525687 = 31525898
- 241 + 31525657 = 31525898
- 331 + 31525567 = 31525898
- 409 + 31525489 = 31525898
Showing the first eight; more decompositions exist.
