Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175980, here are decompositions:

17 + 175963 = 175980
19 + 175961 = 175980
31 + 175949 = 175980
41 + 175939 = 175980
43 + 175937 = 175980
61 + 175919 = 175980
71 + 175909 = 175980
83 + 175897 = 175980

Showing the first eight; more decompositions exist.
