Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468422, here are decompositions:

19 + 31468403 = 31468422
23 + 31468399 = 31468422
31 + 31468391 = 31468422
53 + 31468369 = 31468422
103 + 31468319 = 31468422
151 + 31468271 = 31468422
163 + 31468259 = 31468422
179 + 31468243 = 31468422

Showing the first eight; more decompositions exist.
