Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666876, here are decompositions:

13 + 8666863 = 8666876
37 + 8666839 = 8666876
67 + 8666809 = 8666876
79 + 8666797 = 8666876
103 + 8666773 = 8666876
109 + 8666767 = 8666876
193 + 8666683 = 8666876
397 + 8666479 = 8666876

Showing the first eight; more decompositions exist.
