Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622446, here are decompositions:

17 + 31622429 = 31622446
173 + 31622273 = 31622446
239 + 31622207 = 31622446
257 + 31622189 = 31622446
263 + 31622183 = 31622446
293 + 31622153 = 31622446
467 + 31621979 = 31622446
599 + 31621847 = 31622446

Showing the first eight; more decompositions exist.
