Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688198, here are decompositions:

31 + 8688167 = 8688198
37 + 8688161 = 8688198
41 + 8688157 = 8688198
89 + 8688109 = 8688198
97 + 8688101 = 8688198
131 + 8688067 = 8688198
139 + 8688059 = 8688198
269 + 8687929 = 8688198

Showing the first eight; more decompositions exist.
