Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520406, here are decompositions:

13 + 520393 = 520406
37 + 520369 = 520406
43 + 520363 = 520406
67 + 520339 = 520406
97 + 520309 = 520406
109 + 520297 = 520406
127 + 520279 = 520406
193 + 520213 = 520406

Showing the first eight; more decompositions exist.
