Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162668, here are decompositions:

19 + 162649 = 162668
67 + 162601 = 162668
139 + 162529 = 162668
151 + 162517 = 162668
211 + 162457 = 162668
229 + 162439 = 162668
277 + 162391 = 162668
379 + 162289 = 162668

Showing the first eight; more decompositions exist.
