Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622022, here are decompositions:

41 + 31621981 = 31622022
43 + 31621979 = 31622022
59 + 31621963 = 31622022
73 + 31621949 = 31622022
191 + 31621831 = 31622022
269 + 31621753 = 31622022
283 + 31621739 = 31622022
349 + 31621673 = 31622022

Showing the first eight; more decompositions exist.
