Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533000, here are decompositions:
- 19 + 31532981 = 31533000
- 29 + 31532971 = 31533000
- 41 + 31532959 = 31533000
- 61 + 31532939 = 31533000
- 101 + 31532899 = 31533000
- 127 + 31532873 = 31533000
- 137 + 31532863 = 31533000
- 167 + 31532833 = 31533000
Showing the first eight; more decompositions exist.
