Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727166, here are decompositions:

3 + 8727163 = 8727166
5 + 8727161 = 8727166
17 + 8727149 = 8727166
47 + 8727119 = 8727166
53 + 8727113 = 8727166
83 + 8727083 = 8727166
113 + 8727053 = 8727166
179 + 8726987 = 8727166

Showing the first eight; more decompositions exist.
