Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469420, here are decompositions:

13 + 31469407 = 31469420
67 + 31469353 = 31469420
97 + 31469323 = 31469420
127 + 31469293 = 31469420
181 + 31469239 = 31469420
211 + 31469209 = 31469420
223 + 31469197 = 31469420
277 + 31469143 = 31469420

Showing the first eight; more decompositions exist.
