Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736186, here are decompositions:

7 + 8736179 = 8736186
13 + 8736173 = 8736186
47 + 8736139 = 8736186
59 + 8736127 = 8736186
89 + 8736097 = 8736186
97 + 8736089 = 8736186
113 + 8736073 = 8736186
127 + 8736059 = 8736186

Showing the first eight; more decompositions exist.
