Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71968, here are decompositions:

5 + 71963 = 71968
59 + 71909 = 71968
89 + 71879 = 71968
101 + 71867 = 71968
107 + 71861 = 71968
131 + 71837 = 71968
179 + 71789 = 71968
191 + 71777 = 71968

Showing the first eight; more decompositions exist.
