Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170904, here are decompositions:

5 + 170899 = 170904
17 + 170887 = 170904
23 + 170881 = 170904
31 + 170873 = 170904
47 + 170857 = 170904
53 + 170851 = 170904
61 + 170843 = 170904
67 + 170837 = 170904

Showing the first eight; more decompositions exist.
