Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175878, here are decompositions:

5 + 175873 = 175878
19 + 175859 = 175878
41 + 175837 = 175878
67 + 175811 = 175878
97 + 175781 = 175878
151 + 175727 = 175878
179 + 175699 = 175878
191 + 175687 = 175878

Showing the first eight; more decompositions exist.
