Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533792, here are decompositions:
- 19 + 31533773 = 31533792
- 23 + 31533769 = 31533792
- 29 + 31533763 = 31533792
- 71 + 31533721 = 31533792
- 131 + 31533661 = 31533792
- 151 + 31533641 = 31533792
- 179 + 31533613 = 31533792
- 181 + 31533611 = 31533792
Showing the first eight; more decompositions exist.
