Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488322, here are decompositions:

23 + 31488299 = 31488322
29 + 31488293 = 31488322
233 + 31488089 = 31488322
251 + 31488071 = 31488322
263 + 31488059 = 31488322
269 + 31488053 = 31488322
449 + 31487873 = 31488322
641 + 31487681 = 31488322

Showing the first eight; more decompositions exist.
