Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481730, here are decompositions:

31 + 481699 = 481730
37 + 481693 = 481730
79 + 481651 = 481730
97 + 481633 = 481730
181 + 481549 = 481730
199 + 481531 = 481730
229 + 481501 = 481730
241 + 481489 = 481730

Showing the first eight; more decompositions exist.
