Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165224, here are decompositions:

13 + 165211 = 165224
43 + 165181 = 165224
223 + 165001 = 165224
271 + 164953 = 165224
313 + 164911 = 165224
331 + 164893 = 165224
457 + 164767 = 165224
523 + 164701 = 165224

Showing the first eight; more decompositions exist.
