Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646858, here are decompositions:

5 + 8646853 = 8646858
7 + 8646851 = 8646858
37 + 8646821 = 8646858
41 + 8646817 = 8646858
79 + 8646779 = 8646858
107 + 8646751 = 8646858
137 + 8646721 = 8646858
139 + 8646719 = 8646858

Showing the first eight; more decompositions exist.
