Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478512, here are decompositions:

19 + 478493 = 478512
29 + 478483 = 478512
31 + 478481 = 478512
53 + 478459 = 478512
59 + 478453 = 478512
61 + 478451 = 478512
71 + 478441 = 478512
79 + 478433 = 478512

Showing the first eight; more decompositions exist.
