Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478494, here are decompositions:

11 + 478483 = 478494
13 + 478481 = 478494
41 + 478453 = 478494
43 + 478451 = 478494
53 + 478441 = 478494
61 + 478433 = 478494
67 + 478427 = 478494
73 + 478421 = 478494

Showing the first eight; more decompositions exist.
