Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736156, here are decompositions:

17 + 8736139 = 8736156
29 + 8736127 = 8736156
47 + 8736109 = 8736156
59 + 8736097 = 8736156
67 + 8736089 = 8736156
83 + 8736073 = 8736156
97 + 8736059 = 8736156
223 + 8735933 = 8736156

Showing the first eight; more decompositions exist.
