Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469522, here are decompositions:

3 + 31469519 = 31469522
79 + 31469443 = 31469522
199 + 31469323 = 31469522
223 + 31469299 = 31469522
229 + 31469293 = 31469522
283 + 31469239 = 31469522
313 + 31469209 = 31469522
379 + 31469143 = 31469522

Showing the first eight; more decompositions exist.
