Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71984, here are decompositions:

13 + 71971 = 71984
37 + 71947 = 71984
43 + 71941 = 71984
67 + 71917 = 71984
97 + 71887 = 71984
103 + 71881 = 71984
163 + 71821 = 71984
223 + 71761 = 71984

Showing the first eight; more decompositions exist.
