Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469564, here are decompositions:

3 + 31469561 = 31469564
37 + 31469527 = 31469564
97 + 31469467 = 31469564
157 + 31469407 = 31469564
211 + 31469353 = 31469564
241 + 31469323 = 31469564
271 + 31469293 = 31469564
277 + 31469287 = 31469564

Showing the first eight; more decompositions exist.
