Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518850, here are decompositions:

19 + 518831 = 518850
37 + 518813 = 518850
41 + 518809 = 518850
43 + 518807 = 518850
47 + 518803 = 518850
71 + 518779 = 518850
83 + 518767 = 518850
89 + 518761 = 518850

Showing the first eight; more decompositions exist.
