Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622150, here are decompositions:

3 + 31622147 = 31622150
19 + 31622131 = 31622150
31 + 31622119 = 31622150
37 + 31622113 = 31622150
103 + 31622047 = 31622150
193 + 31621957 = 31622150
271 + 31621879 = 31622150
397 + 31621753 = 31622150

Showing the first eight; more decompositions exist.
