Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622674, here are decompositions:

3 + 31622671 = 31622674
11 + 31622663 = 31622674
137 + 31622537 = 31622674
401 + 31622273 = 31622674
467 + 31622207 = 31622674
491 + 31622183 = 31622674
521 + 31622153 = 31622674
593 + 31622081 = 31622674

Showing the first eight; more decompositions exist.
