Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164574, here are decompositions:

5 + 164569 = 164574
43 + 164531 = 164574
61 + 164513 = 164574
71 + 164503 = 164574
97 + 164477 = 164574
103 + 164471 = 164574
127 + 164447 = 164574
131 + 164443 = 164574

Showing the first eight; more decompositions exist.
