Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 480640, here are decompositions:

53 + 480587 = 480640
71 + 480569 = 480640
107 + 480533 = 480640
113 + 480527 = 480640
131 + 480509 = 480640
137 + 480503 = 480640
179 + 480461 = 480640
191 + 480449 = 480640

Showing the first eight; more decompositions exist.
