Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469768, here are decompositions:

7 + 31469761 = 31469768
37 + 31469731 = 31469768
79 + 31469689 = 31469768
97 + 31469671 = 31469768
139 + 31469629 = 31469768
181 + 31469587 = 31469768
199 + 31469569 = 31469768
241 + 31469527 = 31469768

Showing the first eight; more decompositions exist.
