Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622196, here are decompositions:

7 + 31622189 = 31622196
13 + 31622183 = 31622196
17 + 31622179 = 31622196
29 + 31622167 = 31622196
43 + 31622153 = 31622196
83 + 31622113 = 31622196
149 + 31622047 = 31622196
233 + 31621963 = 31622196

Showing the first eight; more decompositions exist.
