Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469450, here are decompositions:

3 + 31469447 = 31469450
7 + 31469443 = 31469450
43 + 31469407 = 31469450
97 + 31469353 = 31469450
127 + 31469323 = 31469450
151 + 31469299 = 31469450
157 + 31469293 = 31469450
163 + 31469287 = 31469450

Showing the first eight; more decompositions exist.
