Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172026, here are decompositions:

5 + 172021 = 172026
17 + 172009 = 172026
79 + 171947 = 172026
89 + 171937 = 172026
97 + 171929 = 172026
103 + 171923 = 172026
109 + 171917 = 172026
137 + 171889 = 172026

Showing the first eight; more decompositions exist.
