Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533090, here are decompositions:
- 89 + 31533001 = 31533090
- 109 + 31532981 = 31533090
- 131 + 31532959 = 31533090
- 151 + 31532939 = 31533090
- 167 + 31532923 = 31533090
- 191 + 31532899 = 31533090
- 223 + 31532867 = 31533090
- 227 + 31532863 = 31533090
Showing the first eight; more decompositions exist.
