Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171182, here are decompositions:

3 + 171179 = 171182
13 + 171169 = 171182
19 + 171163 = 171182
79 + 171103 = 171182
103 + 171079 = 171182
139 + 171043 = 171182
211 + 170971 = 171182
229 + 170953 = 171182

Showing the first eight; more decompositions exist.
