Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175920, here are decompositions:

11 + 175909 = 175920
23 + 175897 = 175920
29 + 175891 = 175920
47 + 175873 = 175920
61 + 175859 = 175920
67 + 175853 = 175920
83 + 175837 = 175920
109 + 175811 = 175920

Showing the first eight; more decompositions exist.
