Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172366, here are decompositions:

23 + 172343 = 172366
53 + 172313 = 172366
59 + 172307 = 172366
83 + 172283 = 172366
107 + 172259 = 172366
149 + 172217 = 172366
167 + 172199 = 172366
197 + 172169 = 172366

Showing the first eight; more decompositions exist.
