Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478488, here are decompositions:

5 + 478483 = 478488
7 + 478481 = 478488
29 + 478459 = 478488
37 + 478451 = 478488
47 + 478441 = 478488
61 + 478427 = 478488
67 + 478421 = 478488
71 + 478417 = 478488

Showing the first eight; more decompositions exist.
