Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525946, here are decompositions:
- 19 + 31525927 = 31525946
- 37 + 31525909 = 31525946
- 43 + 31525903 = 31525946
- 97 + 31525849 = 31525946
- 163 + 31525783 = 31525946
- 223 + 31525723 = 31525946
- 229 + 31525717 = 31525946
- 337 + 31525609 = 31525946
Showing the first eight; more decompositions exist.
