Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468386, here are decompositions:

17 + 31468369 = 31468386
67 + 31468319 = 31468386
97 + 31468289 = 31468386
127 + 31468259 = 31468386
139 + 31468247 = 31468386
163 + 31468223 = 31468386
227 + 31468159 = 31468386
239 + 31468147 = 31468386

Showing the first eight; more decompositions exist.
