Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172276, here are decompositions:

17 + 172259 = 172276
53 + 172223 = 172276
59 + 172217 = 172276
107 + 172169 = 172276
149 + 172127 = 172276
179 + 172097 = 172276
197 + 172079 = 172276
227 + 172049 = 172276

Showing the first eight; more decompositions exist.
