Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533170, here are decompositions:
- 3 + 31533167 = 31533170
- 37 + 31533133 = 31533170
- 43 + 31533127 = 31533170
- 73 + 31533097 = 31533170
- 79 + 31533091 = 31533170
- 157 + 31533013 = 31533170
- 199 + 31532971 = 31533170
- 211 + 31532959 = 31533170
Showing the first eight; more decompositions exist.
