Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178468, here are decompositions:

29 + 178439 = 178468
71 + 178397 = 178468
107 + 178361 = 178468
167 + 178301 = 178468
179 + 178289 = 178468
281 + 178187 = 178468
317 + 178151 = 178468
401 + 178067 = 178468

Showing the first eight; more decompositions exist.
