Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178708, here are decompositions:

11 + 178697 = 178708
17 + 178691 = 178708
107 + 178601 = 178708
137 + 178571 = 178708
149 + 178559 = 178708
227 + 178481 = 178708
239 + 178469 = 178708
269 + 178439 = 178708

Showing the first eight; more decompositions exist.
