Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481322, here are decompositions:

23 + 31481299 = 31481322
29 + 31481293 = 31481322
71 + 31481251 = 31481322
73 + 31481249 = 31481322
83 + 31481239 = 31481322
151 + 31481171 = 31481322
163 + 31481159 = 31481322
179 + 31481143 = 31481322

Showing the first eight; more decompositions exist.
