Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520216, here are decompositions:

3 + 520213 = 520216
23 + 520193 = 520216
113 + 520103 = 520216
149 + 520067 = 520216
173 + 520043 = 520216
197 + 520019 = 520216
227 + 519989 = 520216
269 + 519947 = 520216

Showing the first eight; more decompositions exist.
