Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532080, here are decompositions:
- 17 + 31532063 = 31532080
- 59 + 31532021 = 31532080
- 113 + 31531967 = 31532080
- 149 + 31531931 = 31532080
- 197 + 31531883 = 31532080
- 263 + 31531817 = 31532080
- 353 + 31531727 = 31532080
- 401 + 31531679 = 31532080
Showing the first eight; more decompositions exist.
