Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689128, here are decompositions:

17 + 8689111 = 8689128
31 + 8689097 = 8689128
59 + 8689069 = 8689128
89 + 8689039 = 8689128
131 + 8688997 = 8689128
137 + 8688991 = 8689128
167 + 8688961 = 8689128
311 + 8688817 = 8689128

Showing the first eight; more decompositions exist.
