Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172164, here are decompositions:

7 + 172157 = 172164
11 + 172153 = 172164
17 + 172147 = 172164
37 + 172127 = 172164
67 + 172097 = 172164
71 + 172093 = 172164
137 + 172027 = 172164
163 + 172001 = 172164

Showing the first eight; more decompositions exist.
