Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736828, here are decompositions:

11 + 8736817 = 8736828
19 + 8736809 = 8736828
29 + 8736799 = 8736828
41 + 8736787 = 8736828
47 + 8736781 = 8736828
101 + 8736727 = 8736828
109 + 8736719 = 8736828
127 + 8736701 = 8736828

Showing the first eight; more decompositions exist.
