Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478858, here are decompositions:

5 + 478853 = 478858
47 + 478811 = 478858
71 + 478787 = 478858
89 + 478769 = 478858
131 + 478727 = 478858
179 + 478679 = 478858
227 + 478631 = 478858
269 + 478589 = 478858

Showing the first eight; more decompositions exist.
