Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178944, here are decompositions:

5 + 178939 = 178944
11 + 178933 = 178944
13 + 178931 = 178944
23 + 178921 = 178944
37 + 178907 = 178944
41 + 178903 = 178944
47 + 178897 = 178944
67 + 178877 = 178944

Showing the first eight; more decompositions exist.
