Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533370, here are decompositions:
- 101 + 31533269 = 31533370
- 179 + 31533191 = 31533370
- 227 + 31533143 = 31533370
- 251 + 31533119 = 31533370
- 269 + 31533101 = 31533370
- 389 + 31532981 = 31533370
- 431 + 31532939 = 31533370
- 503 + 31532867 = 31533370
Showing the first eight; more decompositions exist.
