Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178606, here are decompositions:

3 + 178603 = 178606
5 + 178601 = 178606
47 + 178559 = 178606
137 + 178469 = 178606
167 + 178439 = 178606
257 + 178349 = 178606
317 + 178289 = 178606
347 + 178259 = 178606

Showing the first eight; more decompositions exist.
