Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165996, here are decompositions:

13 + 165983 = 165996
109 + 165887 = 165996
113 + 165883 = 165996
139 + 165857 = 165996
163 + 165833 = 165996
167 + 165829 = 165996
179 + 165817 = 165996
197 + 165799 = 165996

Showing the first eight; more decompositions exist.
