Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689188, here are decompositions:

7 + 8689181 = 8689188
19 + 8689169 = 8689188
47 + 8689141 = 8689188
59 + 8689129 = 8689188
149 + 8689039 = 8689188
191 + 8688997 = 8689188
197 + 8688991 = 8689188
227 + 8688961 = 8689188

Showing the first eight; more decompositions exist.
