Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533166, here are decompositions:
- 17 + 31533149 = 31533166
- 23 + 31533143 = 31533166
- 47 + 31533119 = 31533166
- 167 + 31532999 = 31533166
- 227 + 31532939 = 31533166
- 293 + 31532873 = 31533166
- 389 + 31532777 = 31533166
- 479 + 31532687 = 31533166
Showing the first eight; more decompositions exist.
