Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469316, here are decompositions:

13 + 31469303 = 31469316
17 + 31469299 = 31469316
23 + 31469293 = 31469316
29 + 31469287 = 31469316
37 + 31469279 = 31469316
107 + 31469209 = 31469316
139 + 31469177 = 31469316
173 + 31469143 = 31469316

Showing the first eight; more decompositions exist.
