Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516666, here are decompositions:

13 + 516653 = 516666
23 + 516643 = 516666
43 + 516623 = 516666
47 + 516619 = 516666
67 + 516599 = 516666
79 + 516587 = 516666
103 + 516563 = 516666
127 + 516539 = 516666

Showing the first eight; more decompositions exist.
