Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173210, here are decompositions:

3 + 173207 = 173210
19 + 173191 = 173210
61 + 173149 = 173210
73 + 173137 = 173210
151 + 173059 = 173210
157 + 173053 = 173210
211 + 172999 = 173210
223 + 172987 = 173210

Showing the first eight; more decompositions exist.
