Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639164, here are decompositions:

3 + 8639161 = 8639164
11 + 8639153 = 8639164
41 + 8639123 = 8639164
101 + 8639063 = 8639164
113 + 8639051 = 8639164
137 + 8639027 = 8639164
167 + 8638997 = 8639164
173 + 8638991 = 8639164

Showing the first eight; more decompositions exist.
