Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469822, here are decompositions:
- 61 + 31469761 = 31469822
- 151 + 31469671 = 31469822
- 193 + 31469629 = 31469822
- 199 + 31469623 = 31469822
- 379 + 31469443 = 31469822
- 499 + 31469323 = 31469822
- 523 + 31469299 = 31469822
- 613 + 31469209 = 31469822
Showing the first eight; more decompositions exist.
