Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468466, here are decompositions:

13 + 31468453 = 31468466
19 + 31468447 = 31468466
67 + 31468399 = 31468466
97 + 31468369 = 31468466
223 + 31468243 = 31468466
307 + 31468159 = 31468466
439 + 31468027 = 31468466
499 + 31467967 = 31468466

Showing the first eight; more decompositions exist.
