Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71884, here are decompositions:

3 + 71881 = 71884
5 + 71879 = 71884
17 + 71867 = 71884
23 + 71861 = 71884
41 + 71843 = 71884
47 + 71837 = 71884
107 + 71777 = 71884
173 + 71711 = 71884

Showing the first eight; more decompositions exist.
