Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481806, here are decompositions:

5 + 481801 = 481806
19 + 481787 = 481806
37 + 481769 = 481806
53 + 481753 = 481806
107 + 481699 = 481806
109 + 481697 = 481806
113 + 481693 = 481806
139 + 481667 = 481806

Showing the first eight; more decompositions exist.
