Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178346, here are decompositions:

13 + 178333 = 178346
19 + 178327 = 178346
97 + 178249 = 178346
139 + 178207 = 178346
163 + 178183 = 178346
229 + 178117 = 178346
277 + 178069 = 178346
307 + 178039 = 178346

Showing the first eight; more decompositions exist.
