Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177946, here are decompositions:

3 + 177943 = 177946
17 + 177929 = 177946
29 + 177917 = 177946
53 + 177893 = 177946
59 + 177887 = 177946
107 + 177839 = 177946
149 + 177797 = 177946
269 + 177677 = 177946

Showing the first eight; more decompositions exist.
