Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164544, here are decompositions:

13 + 164531 = 164544
31 + 164513 = 164544
41 + 164503 = 164544
67 + 164477 = 164544
73 + 164471 = 164544
97 + 164447 = 164544
101 + 164443 = 164544
113 + 164431 = 164544

Showing the first eight; more decompositions exist.
