Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178832, here are decompositions:

13 + 178819 = 178832
19 + 178813 = 178832
79 + 178753 = 178832
139 + 178693 = 178832
151 + 178681 = 178832
193 + 178639 = 178832
211 + 178621 = 178832
223 + 178609 = 178832

Showing the first eight; more decompositions exist.
