Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178968, here are decompositions:

17 + 178951 = 178968
29 + 178939 = 178968
37 + 178931 = 178968
47 + 178921 = 178968
59 + 178909 = 178968
61 + 178907 = 178968
71 + 178897 = 178968
79 + 178889 = 178968

Showing the first eight; more decompositions exist.
