Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496384, here are decompositions:

13 + 31496371 = 31496384
67 + 31496317 = 31496384
163 + 31496221 = 31496384
211 + 31496173 = 31496384
223 + 31496161 = 31496384
373 + 31496011 = 31496384
463 + 31495921 = 31496384
487 + 31495897 = 31496384

Showing the first eight; more decompositions exist.
