Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468744, here are decompositions:

17 + 31468727 = 31468744
107 + 31468637 = 31468744
113 + 31468631 = 31468744
173 + 31468571 = 31468744
191 + 31468553 = 31468744
227 + 31468517 = 31468744
233 + 31468511 = 31468744
347 + 31468397 = 31468744

Showing the first eight; more decompositions exist.
