Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518562, here are decompositions:

19 + 518543 = 518562
29 + 518533 = 518562
41 + 518521 = 518562
53 + 518509 = 518562
89 + 518473 = 518562
131 + 518431 = 518562
151 + 518411 = 518562
173 + 518389 = 518562

Showing the first eight; more decompositions exist.
