Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469696, here are decompositions:

7 + 31469689 = 31469696
43 + 31469653 = 31469696
67 + 31469629 = 31469696
73 + 31469623 = 31469696
109 + 31469587 = 31469696
127 + 31469569 = 31469696
229 + 31469467 = 31469696
373 + 31469323 = 31469696

Showing the first eight; more decompositions exist.
