Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622000, here are decompositions:

19 + 31621981 = 31622000
37 + 31621963 = 31622000
43 + 31621957 = 31622000
103 + 31621897 = 31622000
307 + 31621693 = 31622000
331 + 31621669 = 31622000
349 + 31621651 = 31622000
367 + 31621633 = 31622000

Showing the first eight; more decompositions exist.
