Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469676, here are decompositions:

5 + 31469671 = 31469676
23 + 31469653 = 31469676
47 + 31469629 = 31469676
53 + 31469623 = 31469676
89 + 31469587 = 31469676
97 + 31469579 = 31469676
107 + 31469569 = 31469676
113 + 31469563 = 31469676

Showing the first eight; more decompositions exist.
