Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86164, here are decompositions:

3 + 86161 = 86164
47 + 86117 = 86164
53 + 86111 = 86164
137 + 86027 = 86164
173 + 85991 = 86164
233 + 85931 = 86164
311 + 85853 = 86164
317 + 85847 = 86164

Showing the first eight; more decompositions exist.
