Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71970, here are decompositions:

7 + 71963 = 71970
23 + 71947 = 71970
29 + 71941 = 71970
37 + 71933 = 71970
53 + 71917 = 71970
61 + 71909 = 71970
71 + 71899 = 71970
83 + 71887 = 71970

Showing the first eight; more decompositions exist.
