Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518876, here are decompositions:

13 + 518863 = 518876
67 + 518809 = 518876
73 + 518803 = 518876
97 + 518779 = 518876
109 + 518767 = 518876
139 + 518737 = 518876
367 + 518509 = 518876
409 + 518467 = 518876

Showing the first eight; more decompositions exist.
