Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71904, here are decompositions:

5 + 71899 = 71904
17 + 71887 = 71904
23 + 71881 = 71904
37 + 71867 = 71904
43 + 71861 = 71904
61 + 71843 = 71904
67 + 71837 = 71904
83 + 71821 = 71904

Showing the first eight; more decompositions exist.
