Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178588, here are decompositions:

17 + 178571 = 178588
29 + 178559 = 178588
101 + 178487 = 178588
107 + 178481 = 178588
149 + 178439 = 178588
191 + 178397 = 178588
227 + 178361 = 178588
239 + 178349 = 178588

Showing the first eight; more decompositions exist.
