Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518556, here are decompositions:

13 + 518543 = 518556
23 + 518533 = 518556
47 + 518509 = 518556
83 + 518473 = 518556
89 + 518467 = 518556
109 + 518447 = 518556
127 + 518429 = 518556
139 + 518417 = 518556

Showing the first eight; more decompositions exist.
