Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165174, here are decompositions:

13 + 165161 = 165174
41 + 165133 = 165174
71 + 165103 = 165174
127 + 165047 = 165174
137 + 165037 = 165174
173 + 165001 = 165174
211 + 164963 = 165174
263 + 164911 = 165174

Showing the first eight; more decompositions exist.
