Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658858, here are decompositions:

11 + 8658847 = 8658858
29 + 8658829 = 8658858
101 + 8658757 = 8658858
149 + 8658709 = 8658858
179 + 8658679 = 8658858
181 + 8658677 = 8658858
199 + 8658659 = 8658858
239 + 8658619 = 8658858

Showing the first eight; more decompositions exist.
