Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171152, here are decompositions:

61 + 171091 = 171152
73 + 171079 = 171152
103 + 171049 = 171152
109 + 171043 = 171152
181 + 170971 = 171152
199 + 170953 = 171152
271 + 170881 = 171152
379 + 170773 = 171152

Showing the first eight; more decompositions exist.
