Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622556, here are decompositions:

19 + 31622537 = 31622556
37 + 31622519 = 31622556
47 + 31622509 = 31622556
83 + 31622473 = 31622556
89 + 31622467 = 31622556
127 + 31622429 = 31622556
167 + 31622389 = 31622556
179 + 31622377 = 31622556

Showing the first eight; more decompositions exist.
