Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164556, here are decompositions:

43 + 164513 = 164556
53 + 164503 = 164556
79 + 164477 = 164556
107 + 164449 = 164556
109 + 164447 = 164556
113 + 164443 = 164556
127 + 164429 = 164556
137 + 164419 = 164556

Showing the first eight; more decompositions exist.
