Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469366, here are decompositions:

13 + 31469353 = 31469366
43 + 31469323 = 31469366
67 + 31469299 = 31469366
73 + 31469293 = 31469366
79 + 31469287 = 31469366
127 + 31469239 = 31469366
157 + 31469209 = 31469366
223 + 31469143 = 31469366

Showing the first eight; more decompositions exist.
