Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526120, here are decompositions:
- 37 + 31526083 = 31526120
- 139 + 31525981 = 31526120
- 163 + 31525957 = 31526120
- 193 + 31525927 = 31526120
- 211 + 31525909 = 31526120
- 229 + 31525891 = 31526120
- 271 + 31525849 = 31526120
- 337 + 31525783 = 31526120
Showing the first eight; more decompositions exist.
