Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520778, here are decompositions:

19 + 520759 = 520778
31 + 520747 = 520778
61 + 520717 = 520778
79 + 520699 = 520778
157 + 520621 = 520778
211 + 520567 = 520778
229 + 520549 = 520778
331 + 520447 = 520778

Showing the first eight; more decompositions exist.
