Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469996, here are decompositions:
- 7 + 31469989 = 31469996
- 43 + 31469953 = 31469996
- 73 + 31469923 = 31469996
- 139 + 31469857 = 31469996
- 199 + 31469797 = 31469996
- 307 + 31469689 = 31469996
- 367 + 31469629 = 31469996
- 373 + 31469623 = 31469996
Showing the first eight; more decompositions exist.
