Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172516, here are decompositions:

83 + 172433 = 172516
89 + 172427 = 172516
173 + 172343 = 172516
233 + 172283 = 172516
257 + 172259 = 172516
293 + 172223 = 172516
317 + 172199 = 172516
347 + 172169 = 172516

Showing the first eight; more decompositions exist.
