Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468668, here are decompositions:

31 + 31468637 = 31468668
37 + 31468631 = 31468668
71 + 31468597 = 31468668
79 + 31468589 = 31468668
97 + 31468571 = 31468668
109 + 31468559 = 31468668
139 + 31468529 = 31468668
151 + 31468517 = 31468668

Showing the first eight; more decompositions exist.
