Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622108, here are decompositions:

61 + 31622047 = 31622108
127 + 31621981 = 31622108
151 + 31621957 = 31622108
211 + 31621897 = 31622108
229 + 31621879 = 31622108
277 + 31621831 = 31622108
439 + 31621669 = 31622108
457 + 31621651 = 31622108

Showing the first eight; more decompositions exist.
