Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165682, here are decompositions:

29 + 165653 = 165682
71 + 165611 = 165682
113 + 165569 = 165682
131 + 165551 = 165682
149 + 165533 = 165682
233 + 165449 = 165682
239 + 165443 = 165682
389 + 165293 = 165682

Showing the first eight; more decompositions exist.
