Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477878, here are decompositions:

31 + 477847 = 477878
67 + 477811 = 477878
109 + 477769 = 477878
139 + 477739 = 477878
151 + 477727 = 477878
157 + 477721 = 477878
241 + 477637 = 477878
307 + 477571 = 477878

Showing the first eight; more decompositions exist.
