Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518012, here are decompositions:

13 + 517999 = 518012
31 + 517981 = 518012
139 + 517873 = 518012
151 + 517861 = 518012
181 + 517831 = 518012
283 + 517729 = 518012
373 + 517639 = 518012
409 + 517603 = 518012

Showing the first eight; more decompositions exist.
