Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539592, here are decompositions:
- 5 + 31539587 = 31539592
- 23 + 31539569 = 31539592
- 179 + 31539413 = 31539592
- 191 + 31539401 = 31539592
- 239 + 31539353 = 31539592
- 263 + 31539329 = 31539592
- 401 + 31539191 = 31539592
- 449 + 31539143 = 31539592
Showing the first eight; more decompositions exist.
