Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679858, here are decompositions:

17 + 8679841 = 8679858
67 + 8679791 = 8679858
149 + 8679709 = 8679858
181 + 8679677 = 8679858
241 + 8679617 = 8679858
251 + 8679607 = 8679858
277 + 8679581 = 8679858
307 + 8679551 = 8679858

Showing the first eight; more decompositions exist.
