Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622464, here are decompositions:

191 + 31622273 = 31622464
227 + 31622237 = 31622464
257 + 31622207 = 31622464
281 + 31622183 = 31622464
311 + 31622153 = 31622464
317 + 31622147 = 31622464
383 + 31622081 = 31622464
563 + 31621901 = 31622464

Showing the first eight; more decompositions exist.
