Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622274, here are decompositions:

17 + 31622257 = 31622274
37 + 31622237 = 31622274
67 + 31622207 = 31622274
107 + 31622167 = 31622274
127 + 31622147 = 31622274
193 + 31622081 = 31622274
227 + 31622047 = 31622274
293 + 31621981 = 31622274

Showing the first eight; more decompositions exist.
