Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469628, here are decompositions:

5 + 31469623 = 31469628
7 + 31469621 = 31469628
41 + 31469587 = 31469628
59 + 31469569 = 31469628
67 + 31469561 = 31469628
97 + 31469531 = 31469628
101 + 31469527 = 31469628
109 + 31469519 = 31469628

Showing the first eight; more decompositions exist.
