Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478906, here are decompositions:

5 + 478901 = 478906
53 + 478853 = 478906
83 + 478823 = 478906
137 + 478769 = 478906
167 + 478739 = 478906
179 + 478727 = 478906
227 + 478679 = 478906
269 + 478637 = 478906

Showing the first eight; more decompositions exist.
