Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468848, here are decompositions:

71 + 31468777 = 31468848
149 + 31468699 = 31468848
181 + 31468667 = 31468848
211 + 31468637 = 31468848
251 + 31468597 = 31468848
277 + 31468571 = 31468848
331 + 31468517 = 31468848
337 + 31468511 = 31468848

Showing the first eight; more decompositions exist.
