Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164584, here are decompositions:

3 + 164581 = 164584
53 + 164531 = 164584
71 + 164513 = 164584
107 + 164477 = 164584
113 + 164471 = 164584
137 + 164447 = 164584
197 + 164387 = 164584
227 + 164357 = 164584

Showing the first eight; more decompositions exist.
