Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162468, here are decompositions:

11 + 162457 = 162468
17 + 162451 = 162468
29 + 162439 = 162468
79 + 162389 = 162468
109 + 162359 = 162468
179 + 162289 = 162468
181 + 162287 = 162468
191 + 162277 = 162468

Showing the first eight; more decompositions exist.
