Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469040, here are decompositions:
- 7 + 31469033 = 31469040
- 13 + 31469027 = 31469040
- 47 + 31468993 = 31469040
- 73 + 31468967 = 31469040
- 137 + 31468903 = 31469040
- 139 + 31468901 = 31469040
- 179 + 31468861 = 31469040
- 191 + 31468849 = 31469040
Showing the first eight; more decompositions exist.
