Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688166, here are decompositions:

5 + 8688161 = 8688166
23 + 8688143 = 8688166
83 + 8688083 = 8688166
89 + 8688077 = 8688166
107 + 8688059 = 8688166
173 + 8687993 = 8688166
293 + 8687873 = 8688166
467 + 8687699 = 8688166

Showing the first eight; more decompositions exist.
