Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481878, here are decompositions:

11 + 481867 = 481878
17 + 481861 = 481878
29 + 481849 = 481878
31 + 481847 = 481878
41 + 481837 = 481878
71 + 481807 = 481878
109 + 481769 = 481878
127 + 481751 = 481878

Showing the first eight; more decompositions exist.
