Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533200, here are decompositions:
- 67 + 31533133 = 31533200
- 73 + 31533127 = 31533200
- 103 + 31533097 = 31533200
- 109 + 31533091 = 31533200
- 199 + 31533001 = 31533200
- 229 + 31532971 = 31533200
- 241 + 31532959 = 31533200
- 277 + 31532923 = 31533200
Showing the first eight; more decompositions exist.
