Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622016, here are decompositions:

37 + 31621979 = 31622016
53 + 31621963 = 31622016
59 + 31621957 = 31622016
67 + 31621949 = 31622016
137 + 31621879 = 31622016
263 + 31621753 = 31622016
277 + 31621739 = 31622016
313 + 31621703 = 31622016

Showing the first eight; more decompositions exist.
