Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622154, here are decompositions:

7 + 31622147 = 31622154
13 + 31622141 = 31622154
23 + 31622131 = 31622154
41 + 31622113 = 31622154
73 + 31622081 = 31622154
107 + 31622047 = 31622154
173 + 31621981 = 31622154
191 + 31621963 = 31622154

Showing the first eight; more decompositions exist.
