Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172266, here are decompositions:

7 + 172259 = 172266
23 + 172243 = 172266
43 + 172223 = 172266
47 + 172219 = 172266
53 + 172213 = 172266
67 + 172199 = 172266
97 + 172169 = 172266
109 + 172157 = 172266

Showing the first eight; more decompositions exist.
