Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636886, here are decompositions:

17 + 8636869 = 8636886
29 + 8636857 = 8636886
47 + 8636839 = 8636886
67 + 8636819 = 8636886
107 + 8636779 = 8636886
127 + 8636759 = 8636886
149 + 8636737 = 8636886
173 + 8636713 = 8636886

Showing the first eight; more decompositions exist.
