Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165162, here are decompositions:

29 + 165133 = 165162
59 + 165103 = 165162
73 + 165089 = 165162
79 + 165083 = 165162
83 + 165079 = 165162
103 + 165059 = 165162
113 + 165049 = 165162
163 + 164999 = 165162

Showing the first eight; more decompositions exist.
