Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469832, here are decompositions:

19 + 31469813 = 31469832
71 + 31469761 = 31469832
101 + 31469731 = 31469832
109 + 31469723 = 31469832
179 + 31469653 = 31469832
211 + 31469621 = 31469832
263 + 31469569 = 31469832
269 + 31469563 = 31469832

Showing the first eight; more decompositions exist.
