Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469340, here are decompositions:

13 + 31469327 = 31469340
17 + 31469323 = 31469340
37 + 31469303 = 31469340
41 + 31469299 = 31469340
47 + 31469293 = 31469340
53 + 31469287 = 31469340
61 + 31469279 = 31469340
101 + 31469239 = 31469340

Showing the first eight; more decompositions exist.
