Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468678, here are decompositions:

11 + 31468667 = 31468678
41 + 31468637 = 31468678
47 + 31468631 = 31468678
89 + 31468589 = 31468678
107 + 31468571 = 31468678
149 + 31468529 = 31468678
167 + 31468511 = 31468678
179 + 31468499 = 31468678

Showing the first eight; more decompositions exist.
