Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518882, here are decompositions:

19 + 518863 = 518882
73 + 518809 = 518882
79 + 518803 = 518882
103 + 518779 = 518882
139 + 518743 = 518882
193 + 518689 = 518882
271 + 518611 = 518882
349 + 518533 = 518882

Showing the first eight; more decompositions exist.
