Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533192, here are decompositions:
- 43 + 31533149 = 31533192
- 59 + 31533133 = 31533192
- 73 + 31533119 = 31533192
- 101 + 31533091 = 31533192
- 179 + 31533013 = 31533192
- 191 + 31533001 = 31533192
- 193 + 31532999 = 31533192
- 211 + 31532981 = 31533192
Showing the first eight; more decompositions exist.
