Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469634, here are decompositions:

5 + 31469629 = 31469634
11 + 31469623 = 31469634
13 + 31469621 = 31469634
47 + 31469587 = 31469634
71 + 31469563 = 31469634
73 + 31469561 = 31469634
103 + 31469531 = 31469634
107 + 31469527 = 31469634

Showing the first eight; more decompositions exist.
