Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513660, here are decompositions:

11 + 513649 = 513660
19 + 513641 = 513660
29 + 513631 = 513660
67 + 513593 = 513660
127 + 513533 = 513660
131 + 513529 = 513660
149 + 513511 = 513660
151 + 513509 = 513660

Showing the first eight; more decompositions exist.
