Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7970, here are decompositions:

7 + 7963 = 7970
19 + 7951 = 7970
37 + 7933 = 7970
43 + 7927 = 7970
97 + 7873 = 7970
103 + 7867 = 7970
181 + 7789 = 7970
211 + 7759 = 7970

Showing the first eight; more decompositions exist.
