Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165230, here are decompositions:

19 + 165211 = 165230
97 + 165133 = 165230
127 + 165103 = 165230
151 + 165079 = 165230
181 + 165049 = 165230
193 + 165037 = 165230
229 + 165001 = 165230
277 + 164953 = 165230

Showing the first eight; more decompositions exist.
