Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170874, here are decompositions:

17 + 170857 = 170874
23 + 170851 = 170874
31 + 170843 = 170874
37 + 170837 = 170874
47 + 170827 = 170874
61 + 170813 = 170874
73 + 170801 = 170874
97 + 170777 = 170874

Showing the first eight; more decompositions exist.
