Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520384, here are decompositions:

3 + 520381 = 520384
5 + 520379 = 520384
23 + 520361 = 520384
71 + 520313 = 520384
191 + 520193 = 520384
233 + 520151 = 520384
281 + 520103 = 520384
311 + 520073 = 520384

Showing the first eight; more decompositions exist.
