Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533046, here are decompositions:
- 47 + 31532999 = 31533046
- 107 + 31532939 = 31533046
- 173 + 31532873 = 31533046
- 179 + 31532867 = 31533046
- 269 + 31532777 = 31533046
- 353 + 31532693 = 31533046
- 359 + 31532687 = 31533046
- 449 + 31532597 = 31533046
Showing the first eight; more decompositions exist.
