Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172116, here are decompositions:

19 + 172097 = 172116
23 + 172093 = 172116
37 + 172079 = 172116
47 + 172069 = 172116
67 + 172049 = 172116
89 + 172027 = 172116
107 + 172009 = 172116
179 + 171937 = 172116

Showing the first eight; more decompositions exist.
