Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678164, here are decompositions:

3 + 8678161 = 8678164
17 + 8678147 = 8678164
23 + 8678141 = 8678164
71 + 8678093 = 8678164
83 + 8678081 = 8678164
101 + 8678063 = 8678164
107 + 8678057 = 8678164
113 + 8678051 = 8678164

Showing the first eight; more decompositions exist.
