Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469964, here are decompositions:

11 + 31469953 = 31469964
41 + 31469923 = 31469964
61 + 31469903 = 31469964
103 + 31469861 = 31469964
107 + 31469857 = 31469964
151 + 31469813 = 31469964
167 + 31469797 = 31469964
181 + 31469783 = 31469964

Showing the first eight; more decompositions exist.
