Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27970, here are decompositions:

3 + 27967 = 27970
17 + 27953 = 27970
23 + 27947 = 27970
29 + 27941 = 27970
53 + 27917 = 27970
167 + 27803 = 27970
179 + 27791 = 27970
191 + 27779 = 27970

Showing the first eight; more decompositions exist.
