Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520518, here are decompositions:

67 + 520451 = 520518
71 + 520447 = 520518
107 + 520411 = 520518
109 + 520409 = 520518
137 + 520381 = 520518
139 + 520379 = 520518
149 + 520369 = 520518
157 + 520361 = 520518

Showing the first eight; more decompositions exist.
