Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171156, here are decompositions:

53 + 171103 = 171156
79 + 171077 = 171156
103 + 171053 = 171156
107 + 171049 = 171156
109 + 171047 = 171156
113 + 171043 = 171156
127 + 171029 = 171156
149 + 171007 = 171156

Showing the first eight; more decompositions exist.
