Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481530, here are decompositions:

17 + 481513 = 481530
29 + 481501 = 481530
41 + 481489 = 481530
61 + 481469 = 481530
83 + 481447 = 481530
97 + 481433 = 481530
113 + 481417 = 481530
151 + 481379 = 481530

Showing the first eight; more decompositions exist.
