Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71910, here are decompositions:

11 + 71899 = 71910
23 + 71887 = 71910
29 + 71881 = 71910
31 + 71879 = 71910
43 + 71867 = 71910
61 + 71849 = 71910
67 + 71843 = 71910
73 + 71837 = 71910

Showing the first eight; more decompositions exist.
