Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526112, here are decompositions:
- 29 + 31526083 = 31526112
- 43 + 31526069 = 31526112
- 61 + 31526051 = 31526112
- 131 + 31525981 = 31526112
- 193 + 31525919 = 31526112
- 199 + 31525913 = 31526112
- 223 + 31525889 = 31526112
- 263 + 31525849 = 31526112
Showing the first eight; more decompositions exist.
