Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469976, here are decompositions:

23 + 31469953 = 31469976
53 + 31469923 = 31469976
73 + 31469903 = 31469976
127 + 31469849 = 31469976
163 + 31469813 = 31469976
179 + 31469797 = 31469976
193 + 31469783 = 31469976
347 + 31469629 = 31469976

Showing the first eight; more decompositions exist.
