Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622662, here are decompositions:

83 + 31622579 = 31622662
233 + 31622429 = 31622662
293 + 31622369 = 31622662
389 + 31622273 = 31622662
479 + 31622183 = 31622662
509 + 31622153 = 31622662
521 + 31622141 = 31622662
683 + 31621979 = 31622662

Showing the first eight; more decompositions exist.
