Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172576, here are decompositions:

3 + 172573 = 172576
23 + 172553 = 172576
59 + 172517 = 172576
137 + 172439 = 172576
149 + 172427 = 172576
233 + 172343 = 172576
263 + 172313 = 172576
269 + 172307 = 172576

Showing the first eight; more decompositions exist.
