Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520378, here are decompositions:

17 + 520361 = 520378
29 + 520349 = 520378
71 + 520307 = 520378
137 + 520241 = 520378
227 + 520151 = 520378
311 + 520067 = 520378
347 + 520031 = 520378
359 + 520019 = 520378

Showing the first eight; more decompositions exist.
