Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469472, here are decompositions:
- 5 + 31469467 = 31469472
- 29 + 31469443 = 31469472
- 31 + 31469441 = 31469472
- 61 + 31469411 = 31469472
- 149 + 31469323 = 31469472
- 173 + 31469299 = 31469472
- 179 + 31469293 = 31469472
- 193 + 31469279 = 31469472
Showing the first eight; more decompositions exist.
