Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520538, here are decompositions:

127 + 520411 = 520538
157 + 520381 = 520538
181 + 520357 = 520538
199 + 520339 = 520538
229 + 520309 = 520538
241 + 520297 = 520538
409 + 520129 = 520538
541 + 519997 = 520538

Showing the first eight; more decompositions exist.
