Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515584, here are decompositions:

5 + 515579 = 515584
107 + 515477 = 515584
227 + 515357 = 515584
233 + 515351 = 515584
347 + 515237 = 515584
353 + 515231 = 515584
431 + 515153 = 515584
617 + 514967 = 515584

Showing the first eight; more decompositions exist.
