Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468356, here are decompositions:

19 + 31468337 = 31468356
37 + 31468319 = 31468356
67 + 31468289 = 31468356
97 + 31468259 = 31468356
109 + 31468247 = 31468356
113 + 31468243 = 31468356
197 + 31468159 = 31468356
373 + 31467983 = 31468356

Showing the first eight; more decompositions exist.
