Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520418, here are decompositions:

7 + 520411 = 520418
37 + 520381 = 520418
61 + 520357 = 520418
79 + 520339 = 520418
109 + 520309 = 520418
127 + 520291 = 520418
139 + 520279 = 520418
307 + 520111 = 520418

Showing the first eight; more decompositions exist.
