Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171122, here are decompositions:

19 + 171103 = 171122
31 + 171091 = 171122
43 + 171079 = 171122
73 + 171049 = 171122
79 + 171043 = 171122
151 + 170971 = 171122
223 + 170899 = 171122
241 + 170881 = 171122

Showing the first eight; more decompositions exist.
