Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518664, here are decompositions:

7 + 518657 = 518664
43 + 518621 = 518664
53 + 518611 = 518664
67 + 518597 = 518664
131 + 518533 = 518664
191 + 518473 = 518664
193 + 518471 = 518664
197 + 518467 = 518664

Showing the first eight; more decompositions exist.
