Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622230, here are decompositions:

23 + 31622207 = 31622230
41 + 31622189 = 31622230
47 + 31622183 = 31622230
83 + 31622147 = 31622230
89 + 31622141 = 31622230
149 + 31622081 = 31622230
251 + 31621979 = 31622230
281 + 31621949 = 31622230

Showing the first eight; more decompositions exist.
