Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165876, here are decompositions:

19 + 165857 = 165876
43 + 165833 = 165876
47 + 165829 = 165876
59 + 165817 = 165876
97 + 165779 = 165876
127 + 165749 = 165876
157 + 165719 = 165876
163 + 165713 = 165876

Showing the first eight; more decompositions exist.
