Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947878, here are decompositions:

5 + 947873 = 947878
17 + 947861 = 947878
59 + 947819 = 947878
131 + 947747 = 947878
137 + 947741 = 947878
149 + 947729 = 947878
167 + 947711 = 947878
227 + 947651 = 947878

Showing the first eight; more decompositions exist.
