Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178950, here are decompositions:

11 + 178939 = 178950
17 + 178933 = 178950
19 + 178931 = 178950
29 + 178921 = 178950
41 + 178909 = 178950
43 + 178907 = 178950
47 + 178903 = 178950
53 + 178897 = 178950

Showing the first eight; more decompositions exist.
