Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705164, here are decompositions:

5 + 8705159 = 8705164
53 + 8705111 = 8705164
71 + 8705093 = 8705164
107 + 8705057 = 8705164
113 + 8705051 = 8705164
131 + 8705033 = 8705164
191 + 8704973 = 8705164
197 + 8704967 = 8705164

Showing the first eight; more decompositions exist.
