Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481908, here are decompositions:

29 + 481879 = 481908
41 + 481867 = 481908
47 + 481861 = 481908
59 + 481849 = 481908
61 + 481847 = 481908
71 + 481837 = 481908
101 + 481807 = 481908
107 + 481801 = 481908

Showing the first eight; more decompositions exist.
