Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518586, here are decompositions:

7 + 518579 = 518586
43 + 518543 = 518586
53 + 518533 = 518586
113 + 518473 = 518586
139 + 518447 = 518586
157 + 518429 = 518586
197 + 518389 = 518586
199 + 518387 = 518586

Showing the first eight; more decompositions exist.
