Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688288, here are decompositions:

5 + 8688283 = 8688288
17 + 8688271 = 8688288
29 + 8688259 = 8688288
67 + 8688221 = 8688288
79 + 8688209 = 8688288
127 + 8688161 = 8688288
131 + 8688157 = 8688288
179 + 8688109 = 8688288

Showing the first eight; more decompositions exist.
