Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622384, here are decompositions:

7 + 31622377 = 31622384
37 + 31622347 = 31622384
97 + 31622287 = 31622384
103 + 31622281 = 31622384
127 + 31622257 = 31622384
271 + 31622113 = 31622384
337 + 31622047 = 31622384
421 + 31621963 = 31622384

Showing the first eight; more decompositions exist.
