Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672886, here are decompositions:

17 + 8672869 = 8672886
67 + 8672819 = 8672886
97 + 8672789 = 8672886
107 + 8672779 = 8672886
113 + 8672773 = 8672886
163 + 8672723 = 8672886
179 + 8672707 = 8672886
199 + 8672687 = 8672886

Showing the first eight; more decompositions exist.
