Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171180, here are decompositions:

11 + 171169 = 171180
13 + 171167 = 171180
17 + 171163 = 171180
19 + 171161 = 171180
89 + 171091 = 171180
101 + 171079 = 171180
103 + 171077 = 171180
127 + 171053 = 171180

Showing the first eight; more decompositions exist.
