Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177158, here are decompositions:

31 + 177127 = 177158
67 + 177091 = 177158
139 + 177019 = 177158
151 + 177007 = 177158
181 + 176977 = 177158
271 + 176887 = 177158
349 + 176809 = 177158
367 + 176791 = 177158

Showing the first eight; more decompositions exist.
