Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736866, here are decompositions:

13 + 8736853 = 8736866
67 + 8736799 = 8736866
79 + 8736787 = 8736866
139 + 8736727 = 8736866
163 + 8736703 = 8736866
199 + 8736667 = 8736866
283 + 8736583 = 8736866
337 + 8736529 = 8736866

Showing the first eight; more decompositions exist.
