Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469792, here are decompositions:

31 + 31469761 = 31469792
61 + 31469731 = 31469792
103 + 31469689 = 31469792
139 + 31469653 = 31469792
163 + 31469629 = 31469792
223 + 31469569 = 31469792
229 + 31469563 = 31469792
349 + 31469443 = 31469792

Showing the first eight; more decompositions exist.
