Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626198, here are decompositions:

5 + 31626193 = 31626198
7 + 31626191 = 31626198
31 + 31626167 = 31626198
67 + 31626131 = 31626198
89 + 31626109 = 31626198
157 + 31626041 = 31626198
179 + 31626019 = 31626198
211 + 31625987 = 31626198

Showing the first eight; more decompositions exist.
