Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481866, here are decompositions:

5 + 481861 = 481866
17 + 481849 = 481866
19 + 481847 = 481866
23 + 481843 = 481866
29 + 481837 = 481866
53 + 481813 = 481866
59 + 481807 = 481866
79 + 481787 = 481866

Showing the first eight; more decompositions exist.
