Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622722, here are decompositions:

23 + 31622699 = 31622722
29 + 31622693 = 31622722
59 + 31622663 = 31622722
293 + 31622429 = 31622722
353 + 31622369 = 31622722
449 + 31622273 = 31622722
569 + 31622153 = 31622722
641 + 31622081 = 31622722

Showing the first eight; more decompositions exist.
