Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622060, here are decompositions:

13 + 31622047 = 31622060
79 + 31621981 = 31622060
97 + 31621963 = 31622060
103 + 31621957 = 31622060
163 + 31621897 = 31622060
181 + 31621879 = 31622060
229 + 31621831 = 31622060
307 + 31621753 = 31622060

Showing the first eight; more decompositions exist.
