Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165802, here are decompositions:

3 + 165799 = 165802
23 + 165779 = 165802
53 + 165749 = 165802
83 + 165719 = 165802
89 + 165713 = 165802
101 + 165701 = 165802
149 + 165653 = 165802
191 + 165611 = 165802

Showing the first eight; more decompositions exist.
