Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622322, here are decompositions:

29 + 31622293 = 31622322
41 + 31622281 = 31622322
139 + 31622183 = 31622322
181 + 31622141 = 31622322
191 + 31622131 = 31622322
241 + 31622081 = 31622322
359 + 31621963 = 31622322
373 + 31621949 = 31622322

Showing the first eight; more decompositions exist.
