Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469946, here are decompositions:

23 + 31469923 = 31469946
43 + 31469903 = 31469946
89 + 31469857 = 31469946
97 + 31469849 = 31469946
149 + 31469797 = 31469946
163 + 31469783 = 31469946
223 + 31469723 = 31469946
257 + 31469689 = 31469946

Showing the first eight; more decompositions exist.
