Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481686, here are decompositions:

5 + 481681 = 481686
13 + 481673 = 481686
19 + 481667 = 481686
47 + 481639 = 481686
53 + 481633 = 481686
67 + 481619 = 481686
97 + 481589 = 481686
109 + 481577 = 481686

Showing the first eight; more decompositions exist.
