Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481830, here are decompositions:

17 + 481813 = 481830
23 + 481807 = 481830
29 + 481801 = 481830
43 + 481787 = 481830
61 + 481769 = 481830
79 + 481751 = 481830
109 + 481721 = 481830
131 + 481699 = 481830

Showing the first eight; more decompositions exist.
