Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533268, here are decompositions:
- 59 + 31533209 = 31533268
- 101 + 31533167 = 31533268
- 149 + 31533119 = 31533268
- 167 + 31533101 = 31533268
- 269 + 31532999 = 31533268
- 401 + 31532867 = 31533268
- 491 + 31532777 = 31533268
- 761 + 31532507 = 31533268
Showing the first eight; more decompositions exist.
