Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642164, here are decompositions:

5 + 8642159 = 8642164
17 + 8642147 = 8642164
23 + 8642141 = 8642164
53 + 8642111 = 8642164
101 + 8642063 = 8642164
107 + 8642057 = 8642164
131 + 8642033 = 8642164
137 + 8642027 = 8642164

Showing the first eight; more decompositions exist.
