Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516660, here are decompositions:

7 + 516653 = 516660
17 + 516643 = 516660
37 + 516623 = 516660
41 + 516619 = 516660
43 + 516617 = 516660
61 + 516599 = 516660
71 + 516589 = 516660
73 + 516587 = 516660

Showing the first eight; more decompositions exist.
