Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622816, here are decompositions:

7 + 31622809 = 31622816
13 + 31622803 = 31622816
37 + 31622779 = 31622816
73 + 31622743 = 31622816
103 + 31622713 = 31622816
307 + 31622509 = 31622816
349 + 31622467 = 31622816
439 + 31622377 = 31622816

Showing the first eight; more decompositions exist.
