Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525770, here are decompositions:
- 7 + 31525763 = 31525770
- 47 + 31525723 = 31525770
- 53 + 31525717 = 31525770
- 71 + 31525699 = 31525770
- 83 + 31525687 = 31525770
- 113 + 31525657 = 31525770
- 163 + 31525607 = 31525770
- 167 + 31525603 = 31525770
Showing the first eight; more decompositions exist.
