Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171162, here are decompositions:

31 + 171131 = 171162
59 + 171103 = 171162
71 + 171091 = 171162
83 + 171079 = 171162
109 + 171053 = 171162
113 + 171049 = 171162
139 + 171023 = 171162
191 + 170971 = 171162

Showing the first eight; more decompositions exist.
