Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481640, here are decompositions:

7 + 481633 = 481640
109 + 481531 = 481640
127 + 481513 = 481640
139 + 481501 = 481640
151 + 481489 = 481640
193 + 481447 = 481640
223 + 481417 = 481640
277 + 481363 = 481640

Showing the first eight; more decompositions exist.
