Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761128, here are decompositions:

11 + 8761117 = 8761128
29 + 8761099 = 8761128
109 + 8761019 = 8761128
137 + 8760991 = 8761128
151 + 8760977 = 8761128
227 + 8760901 = 8761128
251 + 8760877 = 8761128
317 + 8760811 = 8761128

Showing the first eight; more decompositions exist.
