Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478156, here are decompositions:

17 + 478139 = 478156
89 + 478067 = 478156
179 + 477977 = 478156
257 + 477899 = 478156
293 + 477863 = 478156
317 + 477839 = 478156
347 + 477809 = 478156
359 + 477797 = 478156

Showing the first eight; more decompositions exist.
