Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9970, here are decompositions:

3 + 9967 = 9970
29 + 9941 = 9970
41 + 9929 = 9970
47 + 9923 = 9970
83 + 9887 = 9970
113 + 9857 = 9970
131 + 9839 = 9970
137 + 9833 = 9970

Showing the first eight; more decompositions exist.
