Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478178, here are decompositions:

7 + 478171 = 478178
67 + 478111 = 478178
79 + 478099 = 478178
109 + 478069 = 478178
139 + 478039 = 478178
331 + 477847 = 478178
367 + 477811 = 478178
409 + 477769 = 478178

Showing the first eight; more decompositions exist.
