Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8078, here are decompositions:

19 + 8059 = 8078
61 + 8017 = 8078
67 + 8011 = 8078
127 + 7951 = 8078
151 + 7927 = 8078
199 + 7879 = 8078
211 + 7867 = 8078
337 + 7741 = 8078

Showing the first eight; more decompositions exist.
