Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525940, here are decompositions:
- 13 + 31525927 = 31525940
- 31 + 31525909 = 31525940
- 37 + 31525903 = 31525940
- 157 + 31525783 = 31525940
- 163 + 31525777 = 31525940
- 223 + 31525717 = 31525940
- 241 + 31525699 = 31525940
- 283 + 31525657 = 31525940
Showing the first eight; more decompositions exist.
