Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165152, here are decompositions:

19 + 165133 = 165152
73 + 165079 = 165152
103 + 165049 = 165152
151 + 165001 = 165152
199 + 164953 = 165152
241 + 164911 = 165152
271 + 164881 = 165152
313 + 164839 = 165152

Showing the first eight; more decompositions exist.
