Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172088, here are decompositions:

19 + 172069 = 172088
61 + 172027 = 172088
67 + 172021 = 172088
79 + 172009 = 172088
151 + 171937 = 172088
199 + 171889 = 172088
211 + 171877 = 172088
277 + 171811 = 172088

Showing the first eight; more decompositions exist.
