Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177966, here are decompositions:

13 + 177953 = 177966
17 + 177949 = 177966
23 + 177943 = 177966
37 + 177929 = 177966
53 + 177913 = 177966
59 + 177907 = 177966
73 + 177893 = 177966
79 + 177887 = 177966

Showing the first eight; more decompositions exist.
