Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164536, here are decompositions:

5 + 164531 = 164536
23 + 164513 = 164536
59 + 164477 = 164536
89 + 164447 = 164536
107 + 164429 = 164536
149 + 164387 = 164536
173 + 164363 = 164536
179 + 164357 = 164536

Showing the first eight; more decompositions exist.
