Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533798, here are decompositions:
- 7 + 31533791 = 31533798
- 29 + 31533769 = 31533798
- 137 + 31533661 = 31533798
- 139 + 31533659 = 31533798
- 157 + 31533641 = 31533798
- 167 + 31533631 = 31533798
- 199 + 31533599 = 31533798
- 211 + 31533587 = 31533798
Showing the first eight; more decompositions exist.
