Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469484, here are decompositions:

17 + 31469467 = 31469484
37 + 31469447 = 31469484
41 + 31469443 = 31469484
43 + 31469441 = 31469484
61 + 31469423 = 31469484
73 + 31469411 = 31469484
97 + 31469387 = 31469484
127 + 31469357 = 31469484

Showing the first eight; more decompositions exist.
