Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173220, here are decompositions:

11 + 173209 = 173220
13 + 173207 = 173220
29 + 173191 = 173220
31 + 173189 = 173220
37 + 173183 = 173220
43 + 173177 = 173220
71 + 173149 = 173220
79 + 173141 = 173220

Showing the first eight; more decompositions exist.
