Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481040, here are decompositions:

19 + 481021 = 481040
31 + 481009 = 481040
37 + 481003 = 481040
61 + 480979 = 481040
73 + 480967 = 481040
103 + 480937 = 481040
379 + 480661 = 481040
457 + 480583 = 481040

Showing the first eight; more decompositions exist.
