Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510660, here are decompositions:

41 + 510619 = 510660
43 + 510617 = 510660
47 + 510613 = 510660
71 + 510589 = 510660
79 + 510581 = 510660
107 + 510553 = 510660
109 + 510551 = 510660
131 + 510529 = 510660

Showing the first eight; more decompositions exist.
