Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165284, here are decompositions:

37 + 165247 = 165284
73 + 165211 = 165284
103 + 165181 = 165284
151 + 165133 = 165284
181 + 165103 = 165284
283 + 165001 = 165284
331 + 164953 = 165284
373 + 164911 = 165284

Showing the first eight; more decompositions exist.
