Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71964, here are decompositions:

17 + 71947 = 71964
23 + 71941 = 71964
31 + 71933 = 71964
47 + 71917 = 71964
83 + 71881 = 71964
97 + 71867 = 71964
103 + 71861 = 71964
127 + 71837 = 71964

Showing the first eight; more decompositions exist.
