Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622694, here are decompositions:

7 + 31622687 = 31622694
11 + 31622683 = 31622694
23 + 31622671 = 31622694
31 + 31622663 = 31622694
53 + 31622641 = 31622694
157 + 31622537 = 31622694
227 + 31622467 = 31622694
317 + 31622377 = 31622694

Showing the first eight; more decompositions exist.
