Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12970, here are decompositions:

3 + 12967 = 12970
11 + 12959 = 12970
17 + 12953 = 12970
29 + 12941 = 12970
47 + 12923 = 12970
53 + 12917 = 12970
59 + 12911 = 12970
71 + 12899 = 12970

Showing the first eight; more decompositions exist.
