Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165320, here are decompositions:

3 + 165317 = 165320
7 + 165313 = 165320
73 + 165247 = 165320
109 + 165211 = 165320
139 + 165181 = 165320
241 + 165079 = 165320
271 + 165049 = 165320
283 + 165037 = 165320

Showing the first eight; more decompositions exist.
