Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171200, here are decompositions:

31 + 171169 = 171200
37 + 171163 = 171200
97 + 171103 = 171200
109 + 171091 = 171200
151 + 171049 = 171200
157 + 171043 = 171200
193 + 171007 = 171200
229 + 170971 = 171200

Showing the first eight; more decompositions exist.
