Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526420, here are decompositions:
- 31 + 31526389 = 31526420
- 61 + 31526359 = 31526420
- 103 + 31526317 = 31526420
- 139 + 31526281 = 31526420
- 181 + 31526239 = 31526420
- 193 + 31526227 = 31526420
- 199 + 31526221 = 31526420
- 223 + 31526197 = 31526420
Showing the first eight; more decompositions exist.
