Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622256, here are decompositions:

19 + 31622237 = 31622256
67 + 31622189 = 31622256
73 + 31622183 = 31622256
89 + 31622167 = 31622256
103 + 31622153 = 31622256
109 + 31622147 = 31622256
137 + 31622119 = 31622256
277 + 31621979 = 31622256

Showing the first eight; more decompositions exist.
