Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533424, here are decompositions:
- 11 + 31533413 = 31533424
- 53 + 31533371 = 31533424
- 233 + 31533191 = 31533424
- 257 + 31533167 = 31533424
- 281 + 31533143 = 31533424
- 443 + 31532981 = 31533424
- 557 + 31532867 = 31533424
- 647 + 31532777 = 31533424
Showing the first eight; more decompositions exist.
