Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526216, here are decompositions:
- 3 + 31526213 = 31526216
- 19 + 31526197 = 31526216
- 307 + 31525909 = 31526216
- 313 + 31525903 = 31526216
- 367 + 31525849 = 31526216
- 433 + 31525783 = 31526216
- 439 + 31525777 = 31526216
- 499 + 31525717 = 31526216
Showing the first eight; more decompositions exist.
