Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164928, here are decompositions:

17 + 164911 = 164928
47 + 164881 = 164928
89 + 164839 = 164928
97 + 164831 = 164928
107 + 164821 = 164928
139 + 164789 = 164928
157 + 164771 = 164928
199 + 164729 = 164928

Showing the first eight; more decompositions exist.
