Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172564, here are decompositions:

3 + 172561 = 172564
11 + 172553 = 172564
23 + 172541 = 172564
47 + 172517 = 172564
131 + 172433 = 172564
137 + 172427 = 172564
191 + 172373 = 172564
233 + 172331 = 172564

Showing the first eight; more decompositions exist.
