Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521184, here are decompositions:

5 + 521179 = 521184
7 + 521177 = 521184
11 + 521173 = 521184
17 + 521167 = 521184
23 + 521161 = 521184
31 + 521153 = 521184
47 + 521137 = 521184
137 + 521047 = 521184

Showing the first eight; more decompositions exist.
