Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478458, here are decompositions:

5 + 478453 = 478458
7 + 478451 = 478458
17 + 478441 = 478458
31 + 478427 = 478458
37 + 478421 = 478458
41 + 478417 = 478458
47 + 478411 = 478458
59 + 478399 = 478458

Showing the first eight; more decompositions exist.
