Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626016, here are decompositions:

5 + 31626011 = 31626016
29 + 31625987 = 31626016
47 + 31625969 = 31626016
53 + 31625963 = 31626016
167 + 31625849 = 31626016
173 + 31625843 = 31626016
197 + 31625819 = 31626016
239 + 31625777 = 31626016

Showing the first eight; more decompositions exist.
