Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468708, here are decompositions:

41 + 31468667 = 31468708
71 + 31468637 = 31468708
137 + 31468571 = 31468708
149 + 31468559 = 31468708
179 + 31468529 = 31468708
191 + 31468517 = 31468708
197 + 31468511 = 31468708
311 + 31468397 = 31468708

Showing the first eight; more decompositions exist.
