Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689158, here are decompositions:

17 + 8689141 = 8689158
29 + 8689129 = 8689158
47 + 8689111 = 8689158
61 + 8689097 = 8689158
89 + 8689069 = 8689158
167 + 8688991 = 8689158
197 + 8688961 = 8689158
239 + 8688919 = 8689158

Showing the first eight; more decompositions exist.
