Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478506, here are decompositions:

13 + 478493 = 478506
23 + 478483 = 478506
47 + 478459 = 478506
53 + 478453 = 478506
73 + 478433 = 478506
79 + 478427 = 478506
89 + 478417 = 478506
103 + 478403 = 478506

Showing the first eight; more decompositions exist.
