Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520506, here are decompositions:

59 + 520447 = 520506
73 + 520433 = 520506
79 + 520427 = 520506
83 + 520423 = 520506
97 + 520409 = 520506
113 + 520393 = 520506
127 + 520379 = 520506
137 + 520369 = 520506

Showing the first eight; more decompositions exist.
