Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165382, here are decompositions:

3 + 165379 = 165382
71 + 165311 = 165382
89 + 165293 = 165382
149 + 165233 = 165382
179 + 165203 = 165382
293 + 165089 = 165382
383 + 164999 = 165382
419 + 164963 = 165382

Showing the first eight; more decompositions exist.
