Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520280, here are decompositions:

67 + 520213 = 520280
151 + 520129 = 520280
157 + 520123 = 520280
283 + 519997 = 520280
337 + 519943 = 520280
349 + 519931 = 520280
373 + 519907 = 520280
463 + 519817 = 520280

Showing the first eight; more decompositions exist.
