Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622010, here are decompositions:

29 + 31621981 = 31622010
31 + 31621979 = 31622010
47 + 31621963 = 31622010
53 + 31621957 = 31622010
61 + 31621949 = 31622010
109 + 31621901 = 31622010
113 + 31621897 = 31622010
131 + 31621879 = 31622010

Showing the first eight; more decompositions exist.
