Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178510, here are decompositions:

23 + 178487 = 178510
29 + 178481 = 178510
41 + 178469 = 178510
71 + 178439 = 178510
107 + 178403 = 178510
113 + 178397 = 178510
149 + 178361 = 178510
251 + 178259 = 178510

Showing the first eight; more decompositions exist.
