Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520550, here are decompositions:

3 + 520547 = 520550
103 + 520447 = 520550
127 + 520423 = 520550
139 + 520411 = 520550
157 + 520393 = 520550
181 + 520369 = 520550
193 + 520357 = 520550
211 + 520339 = 520550

Showing the first eight; more decompositions exist.
