Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20164, here are decompositions:

3 + 20161 = 20164
17 + 20147 = 20164
41 + 20123 = 20164
47 + 20117 = 20164
101 + 20063 = 20164
113 + 20051 = 20164
167 + 19997 = 20164
173 + 19991 = 20164

Showing the first eight; more decompositions exist.
