Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469904, here are decompositions:

43 + 31469861 = 31469904
47 + 31469857 = 31469904
107 + 31469797 = 31469904
163 + 31469741 = 31469904
173 + 31469731 = 31469904
181 + 31469723 = 31469904
233 + 31469671 = 31469904
251 + 31469653 = 31469904

Showing the first eight; more decompositions exist.
