Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8030, here are decompositions:

13 + 8017 = 8030
19 + 8011 = 8030
37 + 7993 = 8030
67 + 7963 = 8030
79 + 7951 = 8030
97 + 7933 = 8030
103 + 7927 = 8030
151 + 7879 = 8030

Showing the first eight; more decompositions exist.
