Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626304, here are decompositions:

71 + 31626233 = 31626304
107 + 31626197 = 31626304
113 + 31626191 = 31626304
137 + 31626167 = 31626304
173 + 31626131 = 31626304
251 + 31626053 = 31626304
263 + 31626041 = 31626304
293 + 31626011 = 31626304

Showing the first eight; more decompositions exist.
