Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469470, here are decompositions:
- 3 + 31469467 = 31469470
- 23 + 31469447 = 31469470
- 29 + 31469441 = 31469470
- 47 + 31469423 = 31469470
- 59 + 31469411 = 31469470
- 83 + 31469387 = 31469470
- 113 + 31469357 = 31469470
- 167 + 31469303 = 31469470
Showing the first eight; more decompositions exist.
