Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538306, here are decompositions:

3 + 538303 = 538306
5 + 538301 = 538306
23 + 538283 = 538306
47 + 538259 = 538306
59 + 538247 = 538306
107 + 538199 = 538306
149 + 538157 = 538306
179 + 538127 = 538306

Showing the first eight; more decompositions exist.
