Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468516, here are decompositions:

5 + 31468511 = 31468516
17 + 31468499 = 31468516
113 + 31468403 = 31468516
179 + 31468337 = 31468516
197 + 31468319 = 31468516
227 + 31468289 = 31468516
257 + 31468259 = 31468516
269 + 31468247 = 31468516

Showing the first eight; more decompositions exist.
