Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178370, here are decompositions:

19 + 178351 = 178370
37 + 178333 = 178370
43 + 178327 = 178370
109 + 178261 = 178370
139 + 178231 = 178370
163 + 178207 = 178370
229 + 178141 = 178370
277 + 178093 = 178370

Showing the first eight; more decompositions exist.
