Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510820, here are decompositions:

3 + 510817 = 510820
17 + 510803 = 510820
47 + 510773 = 510820
53 + 510767 = 510820
113 + 510707 = 510820
137 + 510683 = 510820
239 + 510581 = 510820
251 + 510569 = 510820

Showing the first eight; more decompositions exist.
