Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727168, here are decompositions:

5 + 8727163 = 8727168
7 + 8727161 = 8727168
11 + 8727157 = 8727168
19 + 8727149 = 8727168
59 + 8727109 = 8727168
101 + 8727067 = 8727168
137 + 8727031 = 8727168
179 + 8726989 = 8727168

Showing the first eight; more decompositions exist.
