Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173904, here are decompositions:

7 + 173897 = 173904
13 + 173891 = 173904
37 + 173867 = 173904
43 + 173861 = 173904
53 + 173851 = 173904
97 + 173807 = 173904
127 + 173777 = 173904
131 + 173773 = 173904

Showing the first eight; more decompositions exist.
