Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469960, here are decompositions:

7 + 31469953 = 31469960
37 + 31469923 = 31469960
103 + 31469857 = 31469960
163 + 31469797 = 31469960
199 + 31469761 = 31469960
229 + 31469731 = 31469960
271 + 31469689 = 31469960
307 + 31469653 = 31469960

Showing the first eight; more decompositions exist.
