Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688228, here are decompositions:

7 + 8688221 = 8688228
19 + 8688209 = 8688228
61 + 8688167 = 8688228
67 + 8688161 = 8688228
71 + 8688157 = 8688228
127 + 8688101 = 8688228
151 + 8688077 = 8688228
317 + 8687911 = 8688228

Showing the first eight; more decompositions exist.
