Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532922, here are decompositions:
- 23 + 31532899 = 31532922
- 41 + 31532881 = 31532922
- 59 + 31532863 = 31532922
- 89 + 31532833 = 31532922
- 173 + 31532749 = 31532922
- 229 + 31532693 = 31532922
- 263 + 31532659 = 31532922
- 269 + 31532653 = 31532922
Showing the first eight; more decompositions exist.
