Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533080, here are decompositions:
- 67 + 31533013 = 31533080
- 79 + 31533001 = 31533080
- 109 + 31532971 = 31533080
- 157 + 31532923 = 31533080
- 181 + 31532899 = 31533080
- 199 + 31532881 = 31533080
- 331 + 31532749 = 31533080
- 421 + 31532659 = 31533080
Showing the first eight; more decompositions exist.
