Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520284, here are decompositions:

5 + 520279 = 520284
43 + 520241 = 520284
71 + 520213 = 520284
173 + 520111 = 520284
181 + 520103 = 520284
211 + 520073 = 520284
241 + 520043 = 520284
263 + 520021 = 520284

Showing the first eight; more decompositions exist.
