Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478146, here are decompositions:

7 + 478139 = 478146
17 + 478129 = 478146
47 + 478099 = 478146
59 + 478087 = 478146
79 + 478067 = 478146
83 + 478063 = 478146
107 + 478039 = 478146
173 + 477973 = 478146

Showing the first eight; more decompositions exist.
