Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8614878, here are decompositions:

5 + 8614873 = 8614878
11 + 8614867 = 8614878
29 + 8614849 = 8614878
37 + 8614841 = 8614878
47 + 8614831 = 8614878
89 + 8614789 = 8614878
101 + 8614777 = 8614878
149 + 8614729 = 8614878

Showing the first eight; more decompositions exist.
