Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17824, here are decompositions:

17 + 17807 = 17824
41 + 17783 = 17824
167 + 17657 = 17824
197 + 17627 = 17824
227 + 17597 = 17824
251 + 17573 = 17824
347 + 17477 = 17824
353 + 17471 = 17824

Showing the first eight; more decompositions exist.
