Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178964, here are decompositions:

13 + 178951 = 178964
31 + 178933 = 178964
43 + 178921 = 178964
61 + 178903 = 178964
67 + 178897 = 178964
151 + 178813 = 178964
157 + 178807 = 178964
211 + 178753 = 178964

Showing the first eight; more decompositions exist.
