Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173188, here are decompositions:

5 + 173183 = 173188
11 + 173177 = 173188
47 + 173141 = 173188
89 + 173099 = 173188
101 + 173087 = 173188
107 + 173081 = 173188
149 + 173039 = 173188
167 + 173021 = 173188

Showing the first eight; more decompositions exist.
