Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520440, here are decompositions:

7 + 520433 = 520440
13 + 520427 = 520440
17 + 520423 = 520440
29 + 520411 = 520440
31 + 520409 = 520440
47 + 520393 = 520440
59 + 520381 = 520440
61 + 520379 = 520440

Showing the first eight; more decompositions exist.
