Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533056, here are decompositions:
- 43 + 31533013 = 31533056
- 97 + 31532959 = 31533056
- 157 + 31532899 = 31533056
- 193 + 31532863 = 31533056
- 223 + 31532833 = 31533056
- 307 + 31532749 = 31533056
- 397 + 31532659 = 31533056
- 463 + 31532593 = 31533056
Showing the first eight; more decompositions exist.
