Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518830, here are decompositions:

17 + 518813 = 518830
23 + 518807 = 518830
29 + 518801 = 518830
71 + 518759 = 518830
83 + 518747 = 518830
89 + 518741 = 518830
101 + 518729 = 518830
113 + 518717 = 518830

Showing the first eight; more decompositions exist.
