Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469460, here are decompositions:

13 + 31469447 = 31469460
17 + 31469443 = 31469460
19 + 31469441 = 31469460
37 + 31469423 = 31469460
53 + 31469407 = 31469460
73 + 31469387 = 31469460
103 + 31469357 = 31469460
107 + 31469353 = 31469460

Showing the first eight; more decompositions exist.
