Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616022, here are decompositions:

5 + 31616017 = 31616022
13 + 31616009 = 31616022
23 + 31615999 = 31616022
29 + 31615993 = 31616022
43 + 31615979 = 31616022
71 + 31615951 = 31616022
101 + 31615921 = 31616022
103 + 31615919 = 31616022

Showing the first eight; more decompositions exist.
