Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165338, here are decompositions:

7 + 165331 = 165338
109 + 165229 = 165338
127 + 165211 = 165338
157 + 165181 = 165338
337 + 165001 = 165338
457 + 164881 = 165338
499 + 164839 = 165338
571 + 164767 = 165338

Showing the first eight; more decompositions exist.
