Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736864, here are decompositions:

11 + 8736853 = 8736864
47 + 8736817 = 8736864
83 + 8736781 = 8736864
137 + 8736727 = 8736864
163 + 8736701 = 8736864
181 + 8736683 = 8736864
197 + 8736667 = 8736864
211 + 8736653 = 8736864

Showing the first eight; more decompositions exist.
