Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512820, here are decompositions:

17 + 512803 = 512820
23 + 512797 = 512820
41 + 512779 = 512820
53 + 512767 = 512820
59 + 512761 = 512820
73 + 512747 = 512820
79 + 512741 = 512820
103 + 512717 = 512820

Showing the first eight; more decompositions exist.
