Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520868, here are decompositions:

31 + 520837 = 520868
109 + 520759 = 520868
151 + 520717 = 520868
421 + 520447 = 520868
457 + 520411 = 520868
487 + 520381 = 520868
499 + 520369 = 520868
571 + 520297 = 520868

Showing the first eight; more decompositions exist.
