Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699178, here are decompositions:

11 + 8699167 = 8699178
17 + 8699161 = 8699178
101 + 8699077 = 8699178
109 + 8699069 = 8699178
127 + 8699051 = 8699178
139 + 8699039 = 8699178
181 + 8698997 = 8699178
239 + 8698939 = 8699178

Showing the first eight; more decompositions exist.
