Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520288, here are decompositions:

47 + 520241 = 520288
137 + 520151 = 520288
257 + 520031 = 520288
269 + 520019 = 520288
317 + 519971 = 520288
491 + 519797 = 520288
641 + 519647 = 520288
677 + 519611 = 520288

Showing the first eight; more decompositions exist.
