Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526384, here are decompositions:
- 13 + 31526371 = 31526384
- 67 + 31526317 = 31526384
- 103 + 31526281 = 31526384
- 157 + 31526227 = 31526384
- 163 + 31526221 = 31526384
- 193 + 31526191 = 31526384
- 433 + 31525951 = 31526384
- 457 + 31525927 = 31526384
Showing the first eight; more decompositions exist.
