Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469454, here are decompositions:

7 + 31469447 = 31469454
11 + 31469443 = 31469454
13 + 31469441 = 31469454
31 + 31469423 = 31469454
43 + 31469411 = 31469454
47 + 31469407 = 31469454
67 + 31469387 = 31469454
97 + 31469357 = 31469454

Showing the first eight; more decompositions exist.
