Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71168, here are decompositions:

7 + 71161 = 71168
79 + 71089 = 71168
109 + 71059 = 71168
157 + 71011 = 71168
199 + 70969 = 71168
211 + 70957 = 71168
277 + 70891 = 71168
439 + 70729 = 71168

Showing the first eight; more decompositions exist.
