Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616858, here are decompositions:

31 + 8616827 = 8616858
37 + 8616821 = 8616858
97 + 8616761 = 8616858
101 + 8616757 = 8616858
137 + 8616721 = 8616858
139 + 8616719 = 8616858
167 + 8616691 = 8616858
179 + 8616679 = 8616858

Showing the first eight; more decompositions exist.
