Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 946878, here are decompositions:

5 + 946873 = 946878
17 + 946861 = 946878
19 + 946859 = 946878
59 + 946819 = 946878
109 + 946769 = 946878
137 + 946741 = 946878
151 + 946727 = 946878
181 + 946697 = 946878

Showing the first eight; more decompositions exist.
