Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178594, here are decompositions:

23 + 178571 = 178594
107 + 178487 = 178594
113 + 178481 = 178594
191 + 178403 = 178594
197 + 178397 = 178594
233 + 178361 = 178594
293 + 178301 = 178594
347 + 178247 = 178594

Showing the first eight; more decompositions exist.
