Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162028, here are decompositions:

11 + 162017 = 162028
17 + 162011 = 162028
29 + 161999 = 162028
59 + 161969 = 162028
71 + 161957 = 162028
107 + 161921 = 162028
149 + 161879 = 162028
197 + 161831 = 162028

Showing the first eight; more decompositions exist.
