Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761188, here are decompositions:

11 + 8761177 = 8761188
19 + 8761169 = 8761188
31 + 8761157 = 8761188
47 + 8761141 = 8761188
71 + 8761117 = 8761188
89 + 8761099 = 8761188
109 + 8761079 = 8761188
151 + 8761037 = 8761188

Showing the first eight; more decompositions exist.
