Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622210, here are decompositions:

3 + 31622207 = 31622210
31 + 31622179 = 31622210
43 + 31622167 = 31622210
79 + 31622131 = 31622210
97 + 31622113 = 31622210
163 + 31622047 = 31622210
229 + 31621981 = 31622210
313 + 31621897 = 31622210

Showing the first eight; more decompositions exist.
