Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627856, here are decompositions:

5 + 8627851 = 8627856
23 + 8627833 = 8627856
43 + 8627813 = 8627856
47 + 8627809 = 8627856
79 + 8627777 = 8627856
157 + 8627699 = 8627856
163 + 8627693 = 8627856
229 + 8627627 = 8627856

Showing the first eight; more decompositions exist.
