Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162928, here are decompositions:

11 + 162917 = 162928
47 + 162881 = 162928
89 + 162839 = 162928
107 + 162821 = 162928
137 + 162791 = 162928
149 + 162779 = 162928
179 + 162749 = 162928
197 + 162731 = 162928

Showing the first eight; more decompositions exist.
