Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622174, here are decompositions:

7 + 31622167 = 31622174
43 + 31622131 = 31622174
61 + 31622113 = 31622174
127 + 31622047 = 31622174
193 + 31621981 = 31622174
211 + 31621963 = 31622174
277 + 31621897 = 31622174
421 + 31621753 = 31622174

Showing the first eight; more decompositions exist.
