Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533132, here are decompositions:
- 5 + 31533127 = 31533132
- 13 + 31533119 = 31533132
- 31 + 31533101 = 31533132
- 41 + 31533091 = 31533132
- 131 + 31533001 = 31533132
- 151 + 31532981 = 31533132
- 173 + 31532959 = 31533132
- 193 + 31532939 = 31533132
Showing the first eight; more decompositions exist.
