Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164250, here are decompositions:

11 + 164239 = 164250
17 + 164233 = 164250
19 + 164231 = 164250
41 + 164209 = 164250
59 + 164191 = 164250
67 + 164183 = 164250
101 + 164149 = 164250
103 + 164147 = 164250

Showing the first eight; more decompositions exist.
