Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478882, here are decompositions:

3 + 478879 = 478882
11 + 478871 = 478882
29 + 478853 = 478882
59 + 478823 = 478882
71 + 478811 = 478882
113 + 478769 = 478882
251 + 478631 = 478882
293 + 478589 = 478882

Showing the first eight; more decompositions exist.
