Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736120, here are decompositions:

11 + 8736109 = 8736120
23 + 8736097 = 8736120
31 + 8736089 = 8736120
47 + 8736073 = 8736120
59 + 8736061 = 8736120
61 + 8736059 = 8736120
79 + 8736041 = 8736120
83 + 8736037 = 8736120

Showing the first eight; more decompositions exist.
