Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539670, here are decompositions:
- 11 + 31539659 = 31539670
- 83 + 31539587 = 31539670
- 101 + 31539569 = 31539670
- 257 + 31539413 = 31539670
- 269 + 31539401 = 31539670
- 293 + 31539377 = 31539670
- 317 + 31539353 = 31539670
- 479 + 31539191 = 31539670
Showing the first eight; more decompositions exist.
