Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533210, here are decompositions:
- 19 + 31533191 = 31533210
- 43 + 31533167 = 31533210
- 61 + 31533149 = 31533210
- 67 + 31533143 = 31533210
- 83 + 31533127 = 31533210
- 109 + 31533101 = 31533210
- 113 + 31533097 = 31533210
- 197 + 31533013 = 31533210
Showing the first eight; more decompositions exist.
