Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698128, here are decompositions:

7 + 8698121 = 8698128
17 + 8698111 = 8698128
31 + 8698097 = 8698128
67 + 8698061 = 8698128
79 + 8698049 = 8698128
151 + 8697977 = 8698128
157 + 8697971 = 8698128
181 + 8697947 = 8698128

Showing the first eight; more decompositions exist.
