Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469304, here are decompositions:

5 + 31469299 = 31469304
11 + 31469293 = 31469304
17 + 31469287 = 31469304
107 + 31469197 = 31469304
127 + 31469177 = 31469304
173 + 31469131 = 31469304
263 + 31469041 = 31469304
271 + 31469033 = 31469304

Showing the first eight; more decompositions exist.
