Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622100, here are decompositions:

19 + 31622081 = 31622100
53 + 31622047 = 31622100
137 + 31621963 = 31622100
151 + 31621949 = 31622100
199 + 31621901 = 31622100
269 + 31621831 = 31622100
347 + 31621753 = 31622100
397 + 31621703 = 31622100

Showing the first eight; more decompositions exist.
