Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169026, here are decompositions:

7 + 169019 = 169026
17 + 169009 = 169026
19 + 169007 = 169026
23 + 169003 = 169026
83 + 168943 = 169026
89 + 168937 = 169026
113 + 168913 = 169026
127 + 168899 = 169026

Showing the first eight; more decompositions exist.
