Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510666, here are decompositions:

47 + 510619 = 510666
53 + 510613 = 510666
83 + 510583 = 510666
97 + 510569 = 510666
113 + 510553 = 510666
137 + 510529 = 510666
263 + 510403 = 510666
283 + 510383 = 510666

Showing the first eight; more decompositions exist.
