Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518610, here are decompositions:

13 + 518597 = 518610
23 + 518587 = 518610
31 + 518579 = 518610
67 + 518543 = 518610
89 + 518521 = 518610
101 + 518509 = 518610
137 + 518473 = 518610
139 + 518471 = 518610

Showing the first eight; more decompositions exist.
