Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688172, here are decompositions:

5 + 8688167 = 8688172
11 + 8688161 = 8688172
29 + 8688143 = 8688172
71 + 8688101 = 8688172
89 + 8688083 = 8688172
113 + 8688059 = 8688172
179 + 8687993 = 8688172
191 + 8687981 = 8688172

Showing the first eight; more decompositions exist.
