Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71892, here are decompositions:

5 + 71887 = 71892
11 + 71881 = 71892
13 + 71879 = 71892
31 + 71861 = 71892
43 + 71849 = 71892
71 + 71821 = 71892
83 + 71809 = 71892
103 + 71789 = 71892

Showing the first eight; more decompositions exist.
