Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165366, here are decompositions:

17 + 165349 = 165366
23 + 165343 = 165366
53 + 165313 = 165366
73 + 165293 = 165366
79 + 165287 = 165366
137 + 165229 = 165366
163 + 165203 = 165366
193 + 165173 = 165366

Showing the first eight; more decompositions exist.
