Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533230, here are decompositions:
- 97 + 31533133 = 31533230
- 103 + 31533127 = 31533230
- 139 + 31533091 = 31533230
- 229 + 31533001 = 31533230
- 271 + 31532959 = 31533230
- 307 + 31532923 = 31533230
- 331 + 31532899 = 31533230
- 349 + 31532881 = 31533230
Showing the first eight; more decompositions exist.
