Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659164, here are decompositions:

11 + 8659153 = 8659164
43 + 8659121 = 8659164
67 + 8659097 = 8659164
97 + 8659067 = 8659164
103 + 8659061 = 8659164
113 + 8659051 = 8659164
127 + 8659037 = 8659164
167 + 8658997 = 8659164

Showing the first eight; more decompositions exist.
