Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520826, here are decompositions:

13 + 520813 = 520826
67 + 520759 = 520826
79 + 520747 = 520826
109 + 520717 = 520826
127 + 520699 = 520826
193 + 520633 = 520826
277 + 520549 = 520826
379 + 520447 = 520826

Showing the first eight; more decompositions exist.
