Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626196, here are decompositions:

3 + 31626193 = 31626196
5 + 31626191 = 31626196
29 + 31626167 = 31626196
227 + 31625969 = 31626196
233 + 31625963 = 31626196
257 + 31625939 = 31626196
347 + 31625849 = 31626196
353 + 31625843 = 31626196

Showing the first eight; more decompositions exist.
