Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469328, here are decompositions:

5 + 31469323 = 31469328
29 + 31469299 = 31469328
41 + 31469287 = 31469328
89 + 31469239 = 31469328
131 + 31469197 = 31469328
151 + 31469177 = 31469328
197 + 31469131 = 31469328
227 + 31469101 = 31469328

Showing the first eight; more decompositions exist.
