Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533160, here are decompositions:
- 11 + 31533149 = 31533160
- 17 + 31533143 = 31533160
- 41 + 31533119 = 31533160
- 59 + 31533101 = 31533160
- 179 + 31532981 = 31533160
- 293 + 31532867 = 31533160
- 383 + 31532777 = 31533160
- 467 + 31532693 = 31533160
Showing the first eight; more decompositions exist.
