Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533112, here are decompositions:
- 11 + 31533101 = 31533112
- 113 + 31532999 = 31533112
- 131 + 31532981 = 31533112
- 173 + 31532939 = 31533112
- 239 + 31532873 = 31533112
- 419 + 31532693 = 31533112
- 683 + 31532429 = 31533112
- 773 + 31532339 = 31533112
Showing the first eight; more decompositions exist.
