Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538304, here are decompositions:

3 + 538301 = 538304
7 + 538297 = 538304
37 + 538267 = 538304
103 + 538201 = 538304
157 + 538147 = 538304
181 + 538123 = 538304
211 + 538093 = 538304
313 + 537991 = 538304

Showing the first eight; more decompositions exist.
