Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468738, here are decompositions:

11 + 31468727 = 31468738
71 + 31468667 = 31468738
101 + 31468637 = 31468738
107 + 31468631 = 31468738
149 + 31468589 = 31468738
167 + 31468571 = 31468738
179 + 31468559 = 31468738
227 + 31468511 = 31468738

Showing the first eight; more decompositions exist.
