Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626208, here are decompositions:

11 + 31626197 = 31626208
17 + 31626191 = 31626208
41 + 31626167 = 31626208
167 + 31626041 = 31626208
197 + 31626011 = 31626208
227 + 31625981 = 31626208
239 + 31625969 = 31626208
269 + 31625939 = 31626208

Showing the first eight; more decompositions exist.
